Step 1 of 3

K-2 CCSS Strategies Add To: Result Unknown Level 1: Count All 5 + 4 = IIIII IIII Level 2: Counting On Say 5 and then, using your fingers to model, 6, 7, 8, 9 Level 3: Doubles Plus/Minus 5 + 4= 5+ 4= 1 + 4 +4 = 1 + 8 = 9 Add To: Change Unknown Level 1: N/A Level 2: Counting On 5 + = 9 Say 5, and then, using your fingers to model, 6, 7, 8, 9 Level 3: Rearrange 5 + = 9  9 – 5 = 4 Add To: Start Unknown Level 1: Trial and Error + 4 = 9 III IIII IIIII IIII Level 2: N/A Level 3: Commutative Property = 4 = 9  4 + = 9 From there you can solve the problem with a different strategy, such as counting on Take From: Result Unknown Level 1: Taking Away 7 – 2 = IIIIIII Level 2: Counting On/ Down 7 – 2 = Say 2, and then, modeling with your fingers, 3, 4, 5, 6, 7 Level 3: Rearrange 7 – 2 =  2 + = 7  2 = 5 = 7 Take From: Change Unknown Level 1: N/A Level 2: Counting On/ Down 7 - = 5 Say 5, and then , modeling with your fingers, 6, 7 Level 3: Rearrange 7 – = 5  7 – 5 = 2 Take From: Start Unknown Level 1: Trial and Error – 2 = 5 6 – 2 = 4 7 – 2 = 5 Level 2: N/A Level 3: Rearrange – 2 = 5  5 + 2 = 7 * PTTA Problem: There are 4 vanilla cupcakes and 9 chocolate cupcakes. In total there are 13 cupcakes. PTTA: Total Unknown Level 1: Count All 9 + 4 = IIIIIIIIIIII Level 2: Counting On 9 + 4 = Say 9, and then, modeling with your fingers, count up 10, 11, 12, 13 Level 3: Make a 10 9 + 4 = 9 + 4 = 9 + 1 + 3 = 10 + 3 =13 PTTA: Addend Unknown Level 1: N/A Level 2: Counting On 9 + = 13 Say 9, and then, modeling
