Big Idea:

#### Cubes are a great tool to use when exploring length and making measurement comparisons!

#### Fish Eyes is a math story, but it is not focused on length. I use this book to have the students compare the length of the different fish in the story.

#### Students will be introduced to the concept of weight by describing them as heavy or light. They will also explore how to use their prior knowledge to describe the weight of objects.

#### There are a variety of interactive games online that students can use to practice comparing the length of objects.

#### Too Tall Tina is a book about a student who is obsessed with being too tall. It shows examples of many measurement comparisons.

#### Lining up from tallest to shortest is a great way to practice looking at height and exploring the terms shorter and taller.

#### The Kissing Hand by Audrey Penn is a beautiful story about starting school and facing separation. Images from the story can also be used to create a simple math sorting and graphing activity that is perfect for the first day of school!
