CCSS.Math.Content.K.OA.A.3 Decompose numbers less than or equal to 10 into pairs in more than one way, e.g., by using objects or drawings, and record each decomposition by a drawing or equation (e.g., 5 = 2 + 3 and 5 = 4 + 1).
I got this idea from Fairy Dust Teaching Blog's post: Addition Made Easy. I first taught this lesson in whole group. We did Ways to Make Seven using cards and paper clips. (See the step by step instructions from FairyDust.) It definitely worked like magic and every single one of my kinders was successful! Praise the Lord! They had a great time with it too. I found the adorable little heart clothes pins on the dollar isle at Target.
CCSS.Math.Content.K.NBT.A.1 Compose and decompose numbers from 11 to 19 into ten ones and some further ones, e.g., by using objects or drawings, and record each composition or decomposition by a drawing or equation (such as 18 = 10 + 8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones.
This particular standard has been a real doozie for my babies, but I think we are finally getting the hang of it! I love the look on this girl's face! You can tell she is proud of her work, can't you? In this center students simply model the addition fact using Sweethearts candy! I gave my students their own labeled candy bags. The students knew ahead of time that I would give candy to eat if they could return these bags with ALL the candy hearts still inside. If candy won't work for your students you can always use heart shaped erasers, pompoms, or even dry erase markers! Just visit my TPT store for these great Valentine's Day Playdoh and Counting Mats #1-19. If your babies have struggled with this standard too you may also want to check out my Number Sense and Operations Math Pack!
