Students might count one pair of shoes, or two shoes, or the four corners of a shoebox. They might discuss whether two shoes have two shoelaces or four. They might notice surprising patterns and relationships, and they will want to talk about them.

The accompanying teacher's guide explores deep mathematical ideas that may bubble up in a How Many? conversation, such as counting, number language, units, grouping, partitioning, place value, or vocabulary. It will help you anticipate what students might notice, and offers practical suggestions for facilitation rich discussion with students. This powerful bundle includes both the 36-page hardcover student guide and 112-page teacher's guide.
