Join Mrs. Taylor at the ranch as we learn how to multiply using the strategy of "equal groups." There is a math challenge that students may complete after the guided lesson.

In this video, the teacher explains how to solve equal groups problems by drawing an array. They demonstrate how to determine the number of items in each row or column and how to find the total number of items in all.

In this video, the teacher explains how to divide a fraction by a whole number by thinking about equal groups. Using the example of dividing apples, the teacher demonstrates that dividing fractions by whole numbers requires understanding...

In this video, students learn how to solve equal groups word problems by drawing a bar model. The video provides step-by-step examples of how to use the bar model to solve problems involving equal groups, such as dividing books evenly...

This video is a math lesson that teaches viewers about decomposing and composing numbers. The instructor explains that numbers are made up of smaller parts and demonstrates how to break down numbers into their individual units or groups...

In this video, students learn how knowing their 10s facts can help them solve multiplication problems quickly and fluently. The video demonstrates strategies for multiplying by subtracting from groups of 10. The commutative property of...

Sorting Groups of Expressions identifies the differences between equations and expressions by sorting a group of equations and expressions into groups based on the definitions.

This video demonstrates this concept using models and a number line, showing how to determine the product of two integers when one factor is positive and the other is negative. The video provides clear explanations and examples to help...

Miss Palomine sorts her coins so she’ll be ready for the ice cream man. This begins the discussion of grouping things by quantity. She uses Felix Five’s and Simon Seven’s number cards to remind the student about the numbers 5 and 7.

Pupil outcome: I can groups objects equally. Key learning points: - Objects can be divided into groups with the same number in each group. This shows ___ groups with ___ in each group. - The stem sentence ___ is equal to ___ groups of...

In this video, children learn about numbers by counting and comparing different groups of candies. They practice counting from 1 to 10 and learn how to determine which group has more or less candy. They also learn about the symbols for...

In this video, students learn how to write fractions by looking at sets of objects and grouping them into equal parts. The teacher explains that fractions represent equal parts of a whole, whether it's breaking shapes or sets of objects....

In this video, the teacher explains how to prove that a number is even in math by representing it as the sum of two equal addends. They demonstrate this concept using examples and visuals, showing that even numbers can be evenly split...
