Big Ideas: Mathematical situations can be represented using equations, expression, and representations. In this lesson students consider a 1 meter pet race as a context for adding and subtracting within 100. Students calculate total distance and compare distances to determine the award winner for the race. This lesson is designed to pull together all of the ideas that have been explored throughout this unit (ex. making sets of 10 to add and subtract, decomposing, representing on a number line and using number bonds). Vocabulary: representations, models, equation, expression, number bond, difference, compare Special Materials: 100 chart number lines unifix cubes base ten models
