Use this activity to build division and number sense into any snack time or whenever there is a limited set of things to share among a group: If we deal these out, could everyone get two pieces?

In this activity, learners play a game from India similar to Tic-Tac-Toe. Players take turns placing coins on the game board and sliding the coins along the spaces.

In this activity, learners will play a coin toss game where the highest total wins. Combine coin recognition, addition, and probability with a game learners can play on their own.

In this version of a Sumo wrestling bout, players use mathematical skills to move their opponent's counter beyond the track and "out of the ring." Learners reveal playing cards and the player with the

Make snack time into measuring time and learn to read Nutrition Facts labels. Try this when you’re using “pourable” foods, such as cereal, yoghurt, or juice.

In this activity, the learner asks yes-no questions to identify a secret object (similar to Twenty Questions). This game is easy to adapt for different ages and different kinds of contexts.

In this activity, learners try to put together toy bricks—wearing oven mitts on their hands! This activity shows learners how difficult it is to build small things when your tools are too big.

In this activity, learners explore reaction time and challenge themselves to improve their coordination. Do you want to move faster? Catch that ball that you never seem to see in time?

This fun and simple hands-on astronomy activity illustrates the path of light as it reflects off of mirrors and how this is used in telescopes.

In this activity, learners mark their height on a height chart and discover how tall they are in nanometers.

In this activity, learners explore the relative size of the Sun and Earth as well as the distance between them.

In this activity, learners play a guessing game to explore classification.

In this hands-on activity, learners use toothpicks to build different triangles and squares and then use the toothpicks to build and solve some tricky shape puzzles.

In this activity, learners explore how the application of nano-sized "whiskers" can protect clothing from stains.

In this activity, learners play a card game that explores different size scales--macro, micro and nano.

In this activity, learners make an astrolabe, a device used for measuring altitude, including the height of objects in the sky.
