NCTM Illuminations In this math lesson, learners practice addition facts (with sums of 5, 6, 7, and 8) in a concentration-game format using dominoes. Then, learners generate sums of given numbers using a calculator, record the sums on a hundreds chart and look for patterns. This lesson guide includes questions for learners, assessment options, extensions, and reflection questions.

• CCSS.Math.Content.1.OA.C.6: Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).(more info about this benchmark)
