###
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.

###
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.

###
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. **

###
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.**

###
The Picture Graph Party

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

###
Comparing and Representing Teen Numbers

** The students will choose a cup with manipulatives and build that number using a tool of choice. The students will compare their number with a shoulder partner using math language or comparative language and will write in their math journal using a sentence stem and drawing their justification.**

###
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.

Kid2Kid videos on determining the meaning of slope and intercepts in English and Spanish

###
Using Logical Reasoning to Prove Conjectures about Circles

Given conjectures about circles, the student will use deductive reasoning and counterexamples to prove or disprove the conjectures.

###
Generalizing Geometric Properties of Ratios in Similar Figures

Students will investigate patterns to make conjectures about geometric relationships and apply the definition of similarity, in terms of a dilation, to identify similar figures and their proportional sides and congruent corresponding angles.

###
Determining Area: Sectors of Circles

Students will use proportional reasoning to develop formulas to determine the area of sectors of circles. Students will then solve problems involving the area of sectors of circles.

###
Making Conjectures About Circles and Segments

Given examples of circles and the lines that intersect them, the student will use explorations and concrete models to formulate and test conjectures about the properties and relationships among the resulting segments.

###
Determining Area: Regular Polygons and Circles

The student will apply the formula for the area of regular polygons to solve problems.

###
Making Conjectures About Circles and Angles

Given examples of circles and the lines that intersect them, the student will use explorations and concrete models to formulate and test conjectures about the properties of and relationships among the resulting angles.
