## Pages

- [About our toys and learning activities](https://otterden.toys/about/): Den the otter learns by doing. Montessori-aligned toys for small hands: sorting, counting, building sets, dragons, dinosaurs. Made in Armenia.
- [Bead Chain Addition Snake for 6 Year Olds](https://otterden.toys/activities/addition-snake-game/): Bead bars laid end to end, counted off in tens and swapped for ten-bars until the whole snake is tens. Dried beans on pipe cleaners do the entire job.
- [Balance Beam Coin Carry for 5 Year Olds](https://otterden.toys/activities/balance-beam-coin-stack/): A line of tape across the floor, five coins stacked on a saucer, and a walk that only works slowly. Two minutes to set up, and it moves to a kerb outdoors.
- [Balance Board Coin Steady for 3 Year Olds](https://otterden.toys/activities/balance-board-coin-balance/): Standing on something that rocks a centimetre, keeping a coin still on the back of the hand. A bread board on a rolled towel does this, and does it properly.
- [Place Value Bead Bank Game for 5 Year Olds](https://otterden.toys/activities/bank-game-thousand-cubes/): Beans loose, banded in tens, bagged in hundreds. Your child fetches a number from the bank and finds out why ten of one thing becomes one of the next size up.
- [Button Sewing Card for 4 Year Olds](https://otterden.toys/activities/button-sewing-card/): A card punched with pairs of holes, a shoelace with a stiff end, and real buttons sewn on properly. Fifteen minutes to make, and it lives in a bag for weeks.
- [Cardboard Loom Yarn Weaving for 7 Year Olds](https://otterden.toys/activities/cardboard-loom-yarn-weaving/): A loom cut from a cereal box, warped with kitchen string, woven with any yarn in the house. Two hours of work spread over four sittings, and a real cloth at the end.
- [Post Office Sound Drop for 3 Year Olds](https://otterden.toys/activities/cardboard-post-office-phonics-drop/): A shoebox with four letter slots and a stack of hand-drawn picture cards. Your child posts each card into the sound its word starts with, in any language.
- [Cardboard Slotting and Coin Drop for 2 Year Olds](https://otterden.toys/activities/cardboard-slotting-coin-drop/): Slots cut in three directions in a tub lid, and a pile of jar lids to post through them. The wrist has to turn to match the slot, which is the whole job.
- [Clock Face and Hands Match for 5 Year Olds](https://otterden.toys/activities/clock-face-hands-match/): A paper plate clock with two card hands on a split pin, and twelve cards pairing a time with something that really happens in your child's day.
- [Clothespin Pinching for 2 Year Olds](https://otterden.toys/activities/clothespin-pinching/): Wooden pegs clipped around the rim of a bowl. Nothing to buy, nothing to set up, and the strongest pincer workout in the house for a two year old.
- [Color Shade Grading for 3 Year Olds](https://otterden.toys/activities/colour-shade-grading/): Paint chips from the hardware shop, cut into squares and laid out darkest to palest. Two minutes to set up, fits in a coat pocket, and the eye does all the work.
- [Maze Blueprint Mapping for 6 Year Olds](https://otterden.toys/activities/complex-maze-blueprint-mapping/): A maze taped out on the floor, then drawn to scale on squared paper. One shoe length is one square, and the marble has to get from the door to the window.
- [Egg Carton Counting Grid for 4 Year Olds](https://otterden.toys/activities/egg-carton-counting-grid/): Numerals written in the cups of an egg carton, and the matching count of dried beans dropped into each one. Fifteen minutes to make, and then years of use.
- [Continent Map Puzzle for 5 Year Olds](https://otterden.toys/activities/geography-map-puzzle-assembly/): Your child lifts each continent out of a wooden map and puts it back. One minute to set up, twenty minutes of play, and this one has to be bought.
- [Shape Shadow Match for 4 Year Olds](https://otterden.toys/activities/geometric-shape-shadow-match/): Solid shapes stood in a torch beam and matched to their traced outlines on paper. The moment a cylinder casts a rectangle is the reason this one exists.
- [Tongs and Ice Tray Transfer for 2 Year Olds](https://otterden.toys/activities/kitchen-tongs-ice-tray-transfer/): Kitchen tongs, an ice cube tray and twelve cotton wool balls moved across the table one at a time. Nothing to set up, and real tool work at two.
- [Mirror Feelings Copycat for 3 Year Olds](https://otterden.toys/activities/mirror-emotion-copying/): Six faces drawn on cards, copied side by side in a mirror, and the feeling said out loud. Three minutes long, and about naming feelings rather than testing them.
- [Paper Folding Precision for 5 Year Olds](https://otterden.toys/activities/origami-creasing-challenge/): A square of paper and one rule: line the corners up before you press. Four models in ascending difficulty, each one testing its own creases honestly.
- [Painters Tape Floor Balance Track for 4 Year Olds](https://otterden.toys/activities/painters-tape-balance-track/): Your child walks a line of tape on the floor without stepping off. Four minutes to set up, twenty minutes of play, one roll of tape. What if he just runs it.
- [Pattern Card Bead Lacing for 3 Year Olds](https://otterden.toys/activities/pattern-card-bead-lacing/): A row of beads drawn on a card, and a lace with the same row going on in the same order. Penne pasta coloured with felt tips does the job just as well.
- [Peg and Hole Matching for 2 Year Olds](https://otterden.toys/activities/peg-and-hole-matching/): Fat pegs pushed into holes that just fit them. A block of packing foam and a handful of crayons makes the whole thing in five minutes, and it lasts months.
- [Plant Care and Growth Measuring for 6 Year Olds](https://otterden.toys/activities/plant-care-and-measurement/): A bean in a jam jar, watered on a schedule the child owns and measured each morning with a strip of paper. Cress answers in two days, a bean in a fortnight.
- [Posting and Slotting for 2 Year Olds](https://otterden.toys/activities/posting-and-slotting/): One tub, one slot, a handful of milk bottle lids. The disc goes in and it is gone, then the lid comes off and it is back. Two minutes to make, months of use.
- [Nuts and Bolts Screwing for 3 Year Olds](https://otterden.toys/activities/screwing-nuts-and-bolts/): Five fat bolts, five nuts and a tin to keep them in. Jars and their lids do the same job tonight, and both teach the hand turn that later opens doors.
- [Blindfold Rope Path Walk for 4 Year Olds](https://otterden.toys/activities/silent-blindfold-obstacle-walk/): A rope laid along the floor and followed with the eyes closed, steered by your voice. Two minutes to set up, nothing to buy, and no blindfold needed.
- [Soap Carving and Safe Whittling for 6 Year Olds](https://otterden.toys/activities/soap-carving/): Your child carves a shape from a bar of soap with a blunt tool. Five minutes to set up, forty minutes of quiet, nothing bought. Which tool, and why blunt.
- [Sponge Squeezing for 2 Year Olds](https://otterden.toys/activities/sponge-squeezing/): Water carried between two bowls in a sponge. Two minutes to set up, a towel underneath, and the strongest two-handed squeeze a toddler gets to make.
- [Bucket Stilts Balance Track for 6 Year Olds](https://otterden.toys/activities/stilts-and-balance-track/): Two tins with rope handles, walked along a taped line on flat ground. Fifteen minutes to build once, and then weeks of a six year old getting better at it.
- [Story Sequence Cards for 4 Year Olds](https://otterden.toys/activities/story-sequence-cards/): Four cards drawn on the back of a cereal box, put in the order things happened, and then told as a story. Five minutes to make, and they fit in a coat pocket.
- [Straw Blow Ping Pong Race for 3 Year Olds](https://otterden.toys/activities/straw-blow-ping-pong-race/): A ping pong ball blown across the kitchen table through a straw. Nothing to set up, four minutes long, and it is mouth and breath work, which is speech work.
- [Three-Step Instruction Hunt for 3 Year Olds](https://otterden.toys/activities/three-step-command-hunt/): You say three instructions in one breath and your child does all three. No setup at all, nothing to fetch, five minutes. What to do when only one gets done.
- [Tweezer Transfer Challenge for 3 Year Olds](https://otterden.toys/activities/tweezer-transfer-challenge/): Tweezers, twenty dried chickpeas and an egg carton. The three year old step up from the tongs transfer: a finer tool, smaller items, a tighter target.
- [Walking the Balance Line for 2 Year Olds](https://otterden.toys/activities/walking-the-line/): One strip of tape down the middle of the floor, walked slowly from end to end. Two minutes to lay, nothing to buy, and the first real balance game at two.
- [Water Pouring and Transfer for 2 Year Olds](https://otterden.toys/activities/water-pouring-and-transfer/): Your child pours water between two small jugs until the tray is wet. Three minutes to set up, ten minutes of play, nothing to buy. What to say when it stalls.

- [Body Awareness and Position Sense](https://otterden.toys/skills/gross-motor/body-awareness/): Five activities for knowing where your feet and hands are without looking at them: a rope path walked with eyes closed, a coin held still, stilts made from tins.

- [Storytelling and Vocabulary Activities](https://otterden.toys/skills/language/storytelling-and-grammar/): Two activities where the child does the telling: five cards put in the order it happened and the story told back, and the continents named while lifting them out.
- [Nature and Discovery Activities for Children](https://otterden.toys/skills/nature-science/): A bean grown against glass and measured with a paper strip every morning, with the shadow, weight and water activities that do the same noticing work.
- [Nature and Close Observation, Ages 5 to 8](https://otterden.toys/skills/nature-science/nature-and-observation/): A dried bean grown against the glass of a jam jar so the root shows, watered on the child's own schedule and measured with a paper strip every morning for weeks.
- [Simple Science and Cause and Effect](https://otterden.toys/skills/nature-science/simple-science/): One activity that grows into an experiment: a bean in a jar, then a second jar treated differently on purpose, changing one thing and keeping the rest the same.
- [Everyday Life Skills Activities, Ages 2 to 4](https://otterden.toys/skills/practical-life/): Pouring water between two small jugs and wringing a sponge out from bowl to bowl, with the real tools and real jobs that sit on the other shelves.
- [Sensory Play Activities for Ages 3 to 6](https://otterden.toys/skills/senses/): Grading paint chips from darkest to palest, and telling ten identical pots apart by weight alone, with the water and texture work on the other shelves.

- [Focus and Self Control Activities, Ages 2 to 6](https://otterden.toys/skills/social-emotional/focus-and-self-regulation/): Two activities built on self control: walking three metres of taped line slowly at two, and carrying three instructions across a room without help at four.

- [Measuring and Telling Time, Ages 4 to 8](https://otterden.toys/skills/thinking/measuring-time-money/): Three activities where a child measures without a ruler: ten identical pots sorted by weight, a paper clock set to a real Tuesday, a bean measured every morning.
