Having trouble finding math activity pages to match the new Common Core computation methods in your current math adoption? I did, so I created these practice pages for students to demonstrate the CC addition and subtraction strategies. Includes practice for: Open Number Lines, Partial Sums, and Cross Number puzzles for 2 digit numbers. Designed to coincide with 2nd grade math standards:
MACC2NBT.2.7 - Add and subtract within 1000 using concrete models or drawings
MACC2NBT.2.5 - Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction
MACC2NBT.2.9 - Explain why addition and subtraction strategies work, using place value and the properties of operations
If you find these pages helpful, please leave feedback and FOLLOW me! Thanks for looking, and (hopefully) downloading.
