###
Lines of Symmetry

Students will work collaboratively with a partner to discover what is a line of symmetry.

###
Composing and Decomposing a Number

In this lesson, students will learn how to compose a number with base 10 blocks, decompose a ten, and then compose the same number a different way.

###
Communication in Space

Students will work in cooperative groups to create an accurate arrangement of mirrors that work together to relay a laser beam from a Mars space station to Earth’s Mission Control, which will model utilizing satellites in space for communication, an accommodation necessary for manned space exploration.

###
Wrap It Up! Lateral Area and Surface Area of Prisms

Students will be given a net to calculate how much material it would take to cover the surface.

###
Escaping the Nucleus

**Students will work in groups to complete an escape room challenge that replicates the process of gene expression. **

###
Math Problem Solving CAN DRIVE good problem solvers!: 1st grade CAN Drive

**Students will help the principal collect cans for a can food drive. The students will be able to solve math word problems using the UPS✓ (UNDERSTAND what the problem is asking, make a PLAN, SOLVE the problem, and then CHECK to see if the answer makes sense) song/strategy, draw to show their work, and write a number sentence to go with their problem. **

###
Building Stamina During Stations

**Students will participate in differentiated stations based on counting coins, comparing values, and purchasing items within various wants and needs. Students will self-assess their stamina development throughout the lesson.**

###
Decomposing Number Exploration

**Students will decompose a number up to 20 using manipulatives and graphic organizers.**

###
Comparing Box Plots and Dot Plots

This lesson is a 90-minute lesson that can be delivered in one block or split into two 45 minute lessons. The first part of the lesson engages students in a notice/wonder activity that is designed to help students begin to question how data is represented in box plots and dot plots. The second part of the lesson is designed for students to compare data in box plots and dot plots and identify truths and untruths about the representations.

###
Understanding Mathematical Word Problems

The student is expected to represent word problems involving addition and subtraction of whole numbers up to 20 using concrete and pictorial models and number sentences.

###
Amazing Graphs

Students will understand the different representations of graphical data, through reading, listening, and comprehension of a word problem so they can devise a problem solving plan that addresses the entire problem.

###
Biodiversity

**Students will explore biodiversity concepts through several activities including a video, a card sort, think-pair-shares, food webs, and four corners.**

###
Strike a Pose

The students will solve two-step equations through modeling, expressing algebraically, and writing out the steps to their solutions.

###
Rational Number Stations

**Students will visit two different stations and work as a group to add, subtract, multiply, and divide rational numbers.**

###
Stages of Ecological Succession

Students will collaborate on a electronic slideshow presentation and observe, record, and describe the role of ecological succession including both primary and secondary succession.

###
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.

###
Modeling and Solving Two-Step Equations

Students will use various materials to create models of two-step equations. Then, they will take an equation, create their own model, and solve for the variable from the model.
