The document describes a hands-on mathematics classroom where students collaborate to investigate patterns, measure each other's heights, collect and record data, and make estimates using manipulatives. Students work together to extend patterns using cubes, measure and compare heights, gather data on classmate heights and record it, and estimate lengths using hands and pencils before checking with objects.

1. What does mathematics look like in the Unicorn’s classroom? Hands - On! Collaborating Investigating Exploring Recording Gathering Data Interpreting Having Fun Playing Games Using manipulatives

2. We make patterns using cubes! These friends decided to work together to see if they could make their pattern longer than both of them joined!

3. We work collaboratively to measure each other and then see who is tallest and who is shortest. We put everyone’s measurements together so we can compare heights

4. We collect data on how tall we are and then we record it in our math books.

5. We estimate how many hands and pencils long we think our classmate will be. Then we check our guess using concrete objects!
