Help your students to develop strategies for, and fluency in, addition of two addends to 20 with this comprehensive set. Children use practice pages, games, and songs to master the Commutative Property of Addition; the “Counting On” strategy; memorizing "Doubles;" how to use “Doubles” to solve harder problems; memorizing "Tens;" and how to use “Tens” to solve harder problems.
The 67 practice pages begin by illustrating the concepts using pictures. Next, children learn to shade pictures using two different colors to match the problems. Then, they complete problems without using pictures. Finally, they write about their thinking. Use these as teaching tools, classwork, homework, and assessments. Use the additional 23 pages of games and songs to support learning in whole-group lessons, small-group lessons, and centers.
***Please click on the "Preview" File. When the window opens, click the "Download" icon to get your FREEBIE. I've included a "Counting On" practice page, a page that guides children to write about their thinking, a game, and a song related to this strategy.
***This product aligns to related aspects of the following 1st and 2nd grade Common Core State Standards:
Add ... within 20, demonstrating fluency for addition ... within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); ... and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
Apply properties of operations as strategies to add and subtract. Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) ...
Relate counting to addition ... (e.g., by counting on 2 to add 2).
Fluently add ... within 20 using mental strategies. By end of Grade 2, know from memory all sums of two one-digit numbers.
***I recommend using this packet in conjunction with my "Common Core 1st Grade Math" CD-book set
. It includes all songs in this packet and teaches ALL first grade Common Core math standards using 38 songs.
