- Abstract:
Task Description: The mathematics of the task involves understanding the meaning of base ten and using that understanding to compare the magnitude of numbers. The number line is used as a tool to help articulate understanding of base ten. The mathematics of the unit involves understanding the meaning of base ten and using that understanding to solve number and real life problems. The number line is used as a tool to help articulate understanding of base ten and to solve problems using addition and subtraction of numbers less than one hundred. The focus is on the big idea of going around groups of ten. Strategies will involve applying number properties including distributive, associative, and commutative.
