###
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.

###
Are You Part of Our Family?

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

###
Exploring Number Sense

Students will use manipulatives and a number path to identify numbers one less than or more than a given number.

###
Subtraction Seekers

Students will be introduced to subtraction in an inquiry-based lesson that uses concrete examples and allows students to explore through different settings and scenarios.

###
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.

###
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.

###
Quadratics: Connecting Roots, Zeros, and x-Intercepts

Given a quadratic equation, the student will make connections among the solutions (roots) of the quadratic equation, the zeros of their related functions, and the horizontal intercepts (*x*-intercepts) of the graph of the function.

###
Applying the Laws of Exponents: Verbal/Symbolic

Given verbal and symbolic descriptions of problems involving exponents, the student will simplify the expressions using the laws of exponents.

###
Using the Laws of Exponents to Solve Problems

Given problem situations involving exponents, the student will use the laws of exponents to solve the problems.

###
Formulating Systems of Equations (Verbal → Symbolic)

Given verbal descriptions of situations involving systems of linear equations the student will analyze the situations and formulate systems of equations in two unknowns to solve problems.

###
Solving Quadratic Equations Using Graphs

Given a quadratic equation, the student will use graphical methods to solve the equation.

###
Determining the Meaning of Intercepts

Given algebraic, tabular, and graphical representations of linear functions, the student will determine the intercepts of the function and interpret the meaning of intercepts within the context of the situation.

###
Predicting the Effects of Changing y-Intercepts in Problem Situations

Given verbal, symbolic, numerical, or graphical representations of problem situations, the student will interpret and predict the effects of changing the *y*-intercept in the context of the situations.

###
Solving Linear Inequalities

The student will represent linear inequalities using equations, tables, and graphs. The student will solve linear inequalities using graphs or properties of equality, and determine whether or not a given point is a solution to a linear inequality.
