Today we worked hard to represent numbers! Students learn that we can anchor to 10, and counting large objects is easier when we make groups of 10. We started by estimating how many cubes would be needed to cover the perimeter of a board. Estimates ranged from 23 to 100. We used our place value mats, to find the actual amount. Students grouped individual ones into groups of 10 and then proceded until no more groups could be made. We will continue to work with different manipulitives and repeat this process as we work to build a solid understanding of place value. Oh, and the actual number waws 42!
