Are You Part of Our Family?

**The teacher will introduce Fact Families through literature. Students will create and represent various Fact Families within 10.**

###
The Great Classroom Escape

Students will work collaboratively to solve six real-world multiplication problems and earn puzzle pieces they can put together to reveal a phone number they can call to escape the classroom.

###
Who Ate More - Fractions on a Number Line

In this activity, students will consider a real-world scenario requiring them to compare two fractional amounts using a number line. Through the use of the number line and peer collaboration, students will recognize equivalency in the two fractional quantities and effectively communicate their understanding of this concept.

###
Decoding Word Problems

**This lesson focuses on multi-step word problems involving division along with addition or subtraction. The students chunk word problems into each individual step and learn how to choose a familiar strategy. **

###
What Goes In, Must Come Out

**Students will learn how to use an input-output table using real-world examples.**

###
Understanding the Equal Sign and Balancing Equations

Students will apply addition strategies as they complete four different station rotations to help understand that the equal sign represents a relationship where the expressions on each side of the equal sign represents the same value.

###
Analyzing Data Using a Dot Plot

Students will construct a dot plot using data collected on the faces of a cube after it is rolled. Students will then use a key to change the data to represent a larger population.
