This activity might just be even more fun than our Fizzy Reading activity from a few days ago! It is a similar idea, but includes a super fun math game for kids. It is adaptable to all ages: use one dice for preschoolers and have them “fizz” the corresponding number. Use two dice for older kids and have them add the two numbers together! All ages will have a blast!
Here’s what you’ll need: number ice mold, two dice, a squeeze bottle, baking soda, a shallow baking dish or plastic tray, water, vinegar, and food coloring. Our colorful dice were borrowed from our ThinkFun Math Dice Jr. game.
1. Mix a baking soda and water paste (and food coloring, if you choose) so that it is thin enough to pour into the number mold. Freeze for at least a few hours. (If you want to include 11 and 12, you can make and freeze a second set).
2. Remove the frozen numbers from the mold and place them in a baking dish. Pour some vinegar into a squeeze bottle (along with some food coloring, if you choose).
3. Have your child roll the dice and mentally add the two numbers (our kids just rolled again if the sum equaled an 11 or 12).
For preschoolers: Have them just roll one dice and identify the number by fizzing and then let their partner have a turn.
4. Squirt the sum with the vinegar and then let the other child have a turn.
5. Continue letting each child swap back and forth and “fizz” the numbers with the vinegar.
The first person to dissolve all the numbers wins! And if you don’t have enough vinegar, the first person to completely dissolve one of the numbers wins. :)
