See the attached newsletter below for important dates on our December calendar!
Nov. 30-Dec. 4: Math Standards/Objectives and Essential Questions:
1.OA.C.5 Add and subtract within 20 using strategies such as counting on, counting back, making 10, using fact families and related known facts, and composing/ decomposing numbers with an emphasis on making ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9 or adding 6 + 7 by creating the known equivalent 6 + 4 + 3 = 10 + 3 = 13).
1.OA.C.6 Fluently add and subtract within 20 using mental strategies. By the end of 1st grade, know from memory all sums up to 10.
EQ: How can you use doubles to help you add?
EQ: How can you use what you know about doubles to find other sums?
EQ: What strategies can you use to solve addition fact problems?
