###
Lines of Symmetry

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

###
Fractions with Multi-Step Problems

Students will be able to work collaboratively while baking to find the least common multiples of fractions with unlike denominators and create equivalent fractions, then add or subtract.

###
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.

###
Particular Polygons

Students will be able to classify 2D figures by analyzing their attributes.

###
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.

###
Courts of Measure

Students will use measurement tools to measure the dimensions of the basketball court and calculate the area of the court.

###
Are You Part of Our Family?

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

###
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.

###
Exploring Number Sense

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

###
Trip to the Theme Park

Students will work on a real-world based project in class involving multiplication of decimals requiring budgeting skills.

###
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.

###
Give a Hoot . . . Fraction Scoot

Students will add and subtract unlike denominators using pictorial models and manipulatives. During the lesson, they will use both group and independent work to build confidence as they use a variety of formative assessments to check for understanding. The final activity in the lesson has both application of the concepts being taught and a personal reflection of understanding.

###
Finding Common Denominators

Students will work collaboratively to explore and sketch solutions to real-world addition problems involving fractions with unlike denominators. Students will be given the opportunity to use manipulatives and participate in group discussions to reflect on their learning.

###
Analyzing Bar Graphs: Candy Machines

Working in groups, students will examine a bag of candy to determine if the machine that bags the candy is working properly. They will organize data on the colors of the candy in a frequency table and a bar graph. They will calculate the fraction of each color in the bag and compare the fractions to a quota set up by the factory to determine if the machine needs maintenance. Students will create a report about their findings, write a question that requires students to interpret data represented in a bar graph, and reflect in their journals.

###
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.

###
Measurement Properties for 2-D and 3-D Shapes

**Students will be able to use a problem-solving model, tools and techniques, communication, representations, relationships, and justifications when solving problems involving two-dimensional and three-dimensional shapes. Students will integrate content knowledge and skills so that students are prepared to use mathematics in everyday life, society, and the workplace.**

###
Camping with Fractions

Students will create equivalent fractions using measuring cups to make a trail mix and use the fractions to find the total amount of different ingredients.
