Addition and subtraction within 20 is a second-grade math BUNDLE focused on making ten, adding ten, and using ten to add and subtract. This BUNDLE specifically focuses on establishing 10 as a benchmark number to give students strategies and practice in developing automaticity with larger math facts before moving onto multi-digit addition and subtraction.
In the base-10 number system, understanding how to use 10 as a benchmark number is key for students to obtain fluency and automaticity with their math facts, be able to add and subtract two-digit numbers in their heads, and use place value and compensation strategies with larger numbers. If students can learn how to use 10 to add an subtract smaller numbers within 20, they will have so many tools and strategies at their disposal when adding and subtracting multi-digit numbers.
This BUNDLE is 20% off purchasing the two products individually.
