###
Lines of Symmetry

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

###
Centers in Subtraction

**Students will participate in multiple centers including a guided math center that reinforces subtraction concepts. **

###
45-45-90 Triangles

To learn the pattern of the side lengths of a 45-45-90 triangle, students complete a gallery walk, a card sort activity starting with using the Pythagorean theorem, and activity to locate if there is an error in a presented problem and if so to identify what the error is.

###
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.

###
Are You Part of Our Family?

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

###
More Super Duper Math

**Students will gather objects to compare quantities and justify their answers pictorially and verbally. They will use their vocabulary posters and accountable talk menus to discuss with their partners. **

###
Transformations of Absolute Value Functions

Given an absolute value function, the student will analyze the effect on the graph when f(x) is replaced by af(x), f(bx), f(x – c), and f(x) + d for specific positive and negative real values.

###
The Picture Graph Party

Students will explore and create picture graphs through collaboration and group work.

###
Balancing Act

**Students use a pan balance model and manipulatives to identify a total that balances two parts. The use of the pan balance will help to develop the concept of equality. Students will develop the language of equality by reading and identifying the following expressions; balances, is the same as, is equal to, and equa l before the symbol for equality is introduced. Students will identify an unknown part in a balance situation. Students will communicate ideas, explain, and justify how they solved problems.**

###
It’s All About the Bend, No Breaking

Students will experiment with choosing tools to measure around a previously created pet habitat in preparation for choosing appropriately sized food bowls. Students will use a graphic organizer to record tools chosen and to explain why those tools were or were not a good choice for continuous measurement.

###
Working with Literal Equations

The lesson will provide a conceptual basis for illustrating the parallelism between solving multi-step equations and translating literal equations into solutions for specified variables.

###
Going Beyond with Number Bonds

Students will use number bonds to compose and decompose numbers to 10.

###
The Shapes Around Us

Students will make connections between real-world objects and the attributes of two-dimensional shapes.

###
Interpreting Scatterplots

Given scatterplots that represent problem situations, the student will determine if the data has strong vs weak correlation as well as positive, negative, or no correlation.

###
Making Predictions and Critical Judgments (Table/Verbal)

Given verbal descriptions and tables that represent problem situations, the student will make predictions for real-world problems.

###
Collecting Data and Making Predictions

Given an experimental situation, the student will write linear functions that provide a reasonable fit to data to estimate the solutions and make predictions.

###
Writing Expressions to Model Patterns (Table/Pictorial → Symbolic)

Given a pictorial or tabular representation of a pattern and the value of several of their terms, the student will write a formula for the nth term of a sequences.
