This lesson helps students develop an ability to compare and contrast as they explore two strategies to solve three-digit addition problems. This EL Math lesson can be used alone or alongside Three-Digit Addition Strategies Review.

Perpendicular, intersect, parallel! In this lesson, students work in teams to complete a Frayer Model on each of these terms to become masters of geometry vocabulary. Teach this lesson on its own or as support to the lesson What's My Line?

Provide students with an opportunity to identify the wholes that are correctly divided into halves, thirds, and fourths (equal shares). Use this activity alone as a support lesson or alongside Cookie Fractions Fun.

Allow your students to explore the pros and cons of different strategies used to find the area of rectangles. Use this as a stand alone lesson or as a pre-lesson for the Multiplication and Area in the Community Garden lesson.

Go to any length to test your students' understanding of perimeter calculations. Students will use their understanding of the perimeter of rectangular shapes to create rectangles that have different side measurements but equal perimeters.

Slice those pieces and mix it up! In this lesson that follows “Slice It Up! Part One,” students will begin recognizing different ways to create equal shares in whole shapes, creating a fraction poster by the end of the lesson.

With this lesson, your students will see how the order of the factors does not affect the product in a multiplication expression. Use this on its own or alongside You're On a Roll! Practicing Multiplication Facts.

Help! The numbers in our equations have run away and left their answers alone! In this lesson, students will review their math facts and knowledge to solve Ken Ken like puzzles and bring the numbers back to their places.

Dive deep into using base-ten blocks to solve two-digit subtraction problems with regrouping. This lesson can be used independently or in conjuction with the lesson Double Trouble: Subtraction Practice.

Use this lesson to introduce the tool of base-ten blocks to your students. This scaffolded EL support lesson can be used as a stand-alone activity, or prior to teaching Three-Digit Addition with Base-Ten Models.

Get your students up and moving as they learn the basics of geometry. Your competitive students will love this game and put their new skills to the test with a worksheet.

Use this lesson to introduce composing and decomposing as part of your students’ addition and subtraction toolkits.
