At the Block Sale: Add and Subtract Within 20 (Paperback)
Tara loves dogs and wants to support the local animal shelter. She organizes a neighborhood block sale to raise money. This narrative shows readers strategies needed to fluently subtract and add within ten. This volume should be paired with Yolanda's Yard Sale (9781477720646) from the Rosen Math Readers Program to provide the alternative point of view on the same topic.
