__One Big Pair of Underwear__. The book infuses counting concepts for primary grades in a way that is fun and humorous.

After reading, the students used a chart I created to identify the correct number of objects in the story and then represent that number using connecting cubes. After students built the numbers, their classmates would give them either a Thumbs Up or a Thumbs Down and explain why they agreed or disagreed with the representation. This process allowed us to have interesting conversations about numbers and how some numbers are bigger than others.

By the end of our class discussion, we created the chart below.

I asked, “What do you notice about the cubes?” One student said, “Five is less than ten” and I asked them to prove this to me. Another student pointed to the 4 cubes by the seals and said it is one more than the 3 cubes by the scooters. I also asked students did they see anything that was the same. The students made great discoveries about the numbers 1 through 10 using this book.

Lastly, each student completed a comparison activity using the Number Detective booklets that I created. Check out some of their work. Click here to download the free Number Detective booklet.
