Kindergarten Mathematics Module 5, Topic D

children at school

Topic D leads students beyond teen numbers up to 100 (K.CC.1). They begin by counting up and down to 100 both the regular way (ten, twenty, thirty…) and the Say Ten way (ten, 2 tens, 3 tens…). In Lessons 16 to 18, their work from 11 to 19 sets the foundation for success as they realize the number sequence of 1–9 is repeated over and over again within each decade as they count to 100. Students begin by counting within and then across decades (e.g., 28, 29, 30, 31, 32) (K.CC.2). Students also write the numbers 21 to 100 in Lessons 15 to 17, which goes beyond the Kindergarten standard to the Grade 1 standard 1.NBT.1. Writing numerals 21 to 100 is included here because of the wider range of activities they make possible; students readily accept this challenge, which will not be assessed. The final lesson is an optional exploration of decomposing numbers to 100 on the Rekenrek.
