This semester we have been working on extending our number knowledge by exploring what happens when we combine groups of objects. We have been practicing the skill of counting on to find a total number when objects are combined. Roll & Record In this game, we roll two dot cubes. We determine which dot cube is more by counting the dots or subitizing (knowing immediately by recognizing the visual pattern). Then we 'count on' from the bigger number using the twenty number line as support. For example, if we roll 2 and 7 we count on from 7: "7, 8, 9". Through this game we are learning what happens when two groups of objects (or two numbers) are combined, and how best to organize our counting (counting on). Toss the Chips In this game we can choose any number of chips to start with. Usually we have been choosing 5, 6 or 10. We take turns tossing the chips and sorting them by their colours when they land: one red group and one white group. Then we count how many chips we find in each group and record these numbers. Through this game we are playfully learning different combinations of numbers that equal the same total. Racing Bears Racing Bears is our absolute favourite game! Many children chose to play this with their parents at the Student-Led Conferences. In this game we work together with our partner to roll a dot cube and move four bears towards a jewel. Through this game we are practicing counting and counting on, as well as learning to analyze and evaluate how to make combinations of numbers which equal ten.
