Students will get comfortable ordering numbers while having fun using familiar, everyday objects to "map the room."

So many students love to read books in a series but they don't give much thought to what a series really is. In this lesson students discover the two kinds of book series and apply classifying criteria to examples in the library.

Your young scientists will have tons of fun visiting measurement stations and using tools to measure various objects. They'll even be able to create posters at the end of the activity.

Advance your students from relative measurements to learning about standardized units with this lesson that teaches them about inches and feet by using common classroom objects.

Looking for a fun way to learn about measurement? Inch on over to this engaging lesson. Students will love using their own feet to determine the lengths of different objects.

Students will become more familiar with common metric measurements by matching everyday objects with the metric mass and volume units they would use to measure them.

Let’s get reading and writing! In this lesson, students learn to form and recognize regular plural nouns. But the fun doesn’t stop there. Students will work with counting collections to write sentences about the objects they count.

This math lesson is filled with fun hands-on non-standard measurement activities! The lesson begins with an interactive story then has students explore measurement using several different objects as their tools!

In this lesson, your students will use repeated addition to find the total number of objects in arrays. This lesson will help your students build upon the skills needed to learn multiplication.

Engage students in counting through fun "I Spy" activities! Students gain fluency counting and recording numbers to 30.
