Math

In this module students are introduced to place value using addition and subtraction up to the number 20. Students will extend work with addition and subtraction to the number 1-20, and learn some new strategies along the way. Students move from Level 1 strategy of counting all to the more efficient counting on. Now, they go beyond Level 2, counting on  to learn Level 3 decomposition and composition strategies, informally called make ten or take from ten.
