First Grade Mega Math Practice 1.OA.6 Lots of 1.OA.6 First Grade Math practice for your students working with a variety of math strategies. 1.OA.6 is all about learning addition and subtraction strategies for basic facts within twenty. Gaining a foundation with these strategies will give your students a head start on future math work. Students need many opportunities to work with all new math skills. These strategies are very important for your students to master in order to understand higher level math concepts.

This unit is aligned with the First Grade Common Core Math Standard 1.OA.6:
Add and subtract within 20, demonstrating fluency
for addition and subtraction within 10
(Addition and Subtraction Strategies).

It includes these addition and subtraction strategies:
1.OA.6.a: Counting on and making a ten to add. (17 pages)
1.OA.6.b Decomposing numbers leading to a ten (14 pages)
1.OA.6.c Using the relationship between addition and subtraction (9 pages)
1.OA.6.d Creating equivalent but easier know sums (5 pages)
1.OA.6 Choose your strategy – fluency practice (21 pages)

It includes over sixty pages of practice with a year-round theme. I use these pages during our “written math practice” rotation during math workshop/guided math time. These pages can also be used for early finishers or homework during the time that you teach the 1.OA.6b math strategy. Watch for more MEGA MATH PRACTICE units to come aligned with the Common Core State Standards.

I use ‘guided math’ in my classroom. I begin my teaching time block teaching/spiraling math concepts as a whole group, but most of my math block is devoted to guided practice in small groups followed by independent or small group practice, centers and intervention. I begin my math time every day with a page from my popular Number of the Day series. You may find more math in this “printable” format in my store.

I hope that you and your kids enjoy this fun resource. Check out my store for lots of fun math units including my popular Number of the Day units for grades K-Second.
