This brief video shows students how to enter a fraction into the TI-15 calculator and to add fractions. Students should access to a TI-15 calculator while viewing, This video may be embedded within Google Classroom.

This is one possible method for using the area model for division.

With this division strategy, students divide by breaking the dividend into its expanded form. Then, students use familiar multiplication facts to divide. It is suggested that this would be the first of three strategies for division (preceding partial quotients and the standard algorithm.

This lesson is Day 10 in a series of 12 lessons around fraction equivalences and comparisons.

This video lesson serves as a review of equpartitioning in order to determine the fractional part of an area or length. This is a necessary foundational skill for comparing and finding equivalent fractions.

This lesson is Day 1 in a series of 5 lessons around U.S customary measurement.

This 3rd grade video lesson introduces the U.S. customary measurements for length: inches, feet, and yards. In this lesson, students will learn benchmarks (visuals) for measuring in inches, feet and yards when they don't have standard measurement tools available.

This lesson is Day 1 in a series of 12 lessons around fraction equivalences and comparisons.

This video lesson encourages students to reason about and visualize fractions. The lesson focuses on the ideas that fractions are fair shares and that fractions can be compared. This lesson assumes that students have some initial experiences with fractions.

This lesson is Day 2 in a series of 12 lessons around fraction equivalences and comparisons.

This video lesson uses paper folding to introduce the concept of equivalent fractions. To complete this lesson, make sure you have a square piece of paper (any size) and a crayon

This lesson is Day 2 in a series of 12 lessons around fraction equivalences and comparisons.

This video lesson introduces the idea that fractions can be used to represent 1 whole. To engage in this lesson, students may use virtual circle models from Toy Theater (https://toytheater.com/fraction-circles/)

This lesson is Day 3 in a series of 5 lessons around U.S customary measurement.

This video lesson explores the use of appropriate units for measuring length. Additionally, students will be asked to solve single-step problems involving lengths of distances. No materials are needed for this lesson.

This lesson is Day 4 in a series of 12 lessons around fraction equivalences and comparisons.

This video lesson looks at how we use fractions in the kitchen. Students are challenged to use circle models to find equivalent fractions for a recipe. Students may use virtual circe models from the Toy Theater (https://toytheater.com/fraction-circles/).

This lesson is Day 5 in a series of 5 lessons around U.S customary measurement.

In this video lesson, students learn the difference between weight and capacity as they observe a cookie recipe being made. No materials are needed for this lesson.

This lesson is Day 6 in a series of 12 lessons around fraction equivalences and comparisons.

This video lesson teaches students how to create bar models to compare lengths/distances. Students will need a piece of paper, ruler, scissors, and a pencil. These bar models will also be used for Day 7's lesson.

This video lesson introduces the idea that when comparing two fractions, they must refer to the same size whole. Then, students use fraction strips to compare fractions. Students may use virtual fraction strips from Toy Theater (https://toytheater.com/fraction-strips/)

This super-helpful chart outlines the mental math strategies students should be exposed to through Number Talks in grades K-5.  Each strategy is linked to a video of a teacher introducing/explaining how to use that stratgy.  This chart is the perfect companion for teachers implementing Number Talks in their classrooms!
