Tiggly's new manipulative game, Tiggly Chef Subtraction: 1st Grade Math Game is absolutely awesome. It seems the Chef has been cooking up new recipes and ideas in the Taste Test Laboratory and the app depicts him as a crazy smart scientist experimenting with all sorts of concoctions to fill your tummies with joy! Tiggly has made the sciences come alive by transforming their purpose into something relevant and tangible. Love, Love, Love this idea, as it shows that there is more to some jobs than meets the eye…and when it comes to cooking – a foundation in math, the sciences, and chemistry make for tastier treats. And what’s this? The Chef’s invited you to come into the lab and share your expertise to help him devise some new recipes. So put on those Chef’s whites, roll up your sleeves, and let those creative juices flow. To start – press the “go” button in the lab. This ingenious addition serves as an anchor to draw kids attention to the task and be ready for action.
Now, as we all know, that to truly cook from one’s heart, you need to be precise in measuring your ingredients. Too much or too little will spoil the dish, and that’s where math comes into play. In this lab, kids need to pull out just the right amount from the larder, to get that recipe right. Hmmm, this pot is full of crunchy, salty or chocolatey goods but you only need 3 to go from the pot to the beaker to cook? 5 are in the container, but we need 3. Experiment with pulling some goodies out – (Now - no fingers in the pot for tasting yet). Try removing 1 or 2 at a time at first, until you get the correct amount left inside. Soon enough, you’ll know the answer by heart!
During play, kids experience physically removing ingredients and therefore, are an active part of the process of subtraction. Visually, they see the “whole” and the goal with the end result to achieve. By removing all but what’s needed, they also see the variety of ways of using subtraction to get there. These skills easily translate to the kitchen for baking using a scale or measuring cups or spoons, or some fun and wacky science experiments that can be purchased or found in books at the library! Just make sure they are age appropriate and safe for kids. There are so many careers that use chemistry or measurements and playing early in a child’s life gives them the opportunity to lay down the basics and later have these concepts shaped for generalization to an extended task.
There are three levels of achievement:
• Blue Level – where Chef tastes his brews with shocking and silly results. There are 10 predetermined levels, and 5 left to be created by YOU! At this level children subtract numbers equal to or less than 10. They are also shown the reasoning process step by step. All results are immediate and help a child learn mastery at this level with spatial relationships.
• Green Level – moves a little faster, and chef is beginning to rely on all your mathematical capabilities with 8 predetermined levels and 4 to create subtracting numbers equal to or less than 20. Here children branch out and begin experimenting with near space with tools close at hand, and seeing what is needed and available.
• Purple level – now things are really cooking up in the kitchen! It is getting harder and harder to locate what's in the beakers, numbers are getting bigger, and the demands are harder. Kids are challenged with having to do some mental math with numbers equal to or less than 20. In this level, there are 8 predetermined levels and 4 dishes you create. The purple level also increases the difficulty a little further by having to deal with far space. What's in the beakers is not always visible, and kids need to reach out and problem solve what to do.
With the app, you do not need to use the manipulatives, but the experience is always more fun if you do. Chef will also help keep a tally, but he is relying on you to do the math! Mathematical symbols are introduced on screen and emphasized in relation to task completion. Once the measurement is correct…varoom it’s down the vacuum tube and into the beaker. Then you wait, wait, wait – and see what happens! Once you’ve proven yourself, it’s time for YOU to experiment and cook up some of your own concoctions! Play then is reciprocal and allows kids to truly show their mastery….and who wouldn’t want bragging rights to being the creator of
Snickering Sweet Cream Bubbly Bake?
In summary, Tiggly Subtraction is AWESOME because it’s fun, paced at a rate where children can process and absorb the material by actively participating in the process, and encourages and validates their opinions. I have used this game with slightly younger children with success, and it is fun for adults to play with their children. In addition, it exposes kids to the component skills used in career choices, which is refreshing. It can be played by any child being the assistant, and is gender-neutral and free of bias. In a very subtle way, Tiggly Subtraction: 1st Grade Math Game – rallies for all kids to be who they can be regardless of who they are or where they came from. AND that is the message we all strive to teach. Available on iOS.
