Developing the Concept Division

Using two colors of counting chips, seventh graders review the multiplication of rational numbers and then explore how to divide them. They play an online game, "Multiplying and Dividing Signed Numbers," and afterward they devise sign...

Can Dan make a conjecture about dividing fractions with the same denominators? That is what your scholars are to determine. They must show that if the statement is true, they understand how the quantities were determined, and how the...

Use a unit approach in developing a fraction division strategy. The teacher leads a discussion on division containing units, resulting in a connection between the units and like denominators. Pupils develop a rule in dividing fractions...

Provide a meaningful context for learning about the division of fractions with this upper-elementary math lesson. Presented with a simple, real-world problem, young mathematicians work in small groups to develop visual models that help...

Build on the concepts of shared and repeated subtraction division. The teacher guides the class through using both methods for solving a word problem, including formulating an equation. After pairing off for independent practice, one...

Don't table the resource on writing expressions for relationships in tables. Scholars investigate relationships between variables and write algebraic expressions involving multiplication and division. These expressions help solve...

Use base-ten blocks to give your class a hands-on approach to division. Guide them through several problems on the overhead, translating the array into a written equation. This lesson focuses on a problem with no remainder that divides a...

Here is an exponents lesson which invites learners to examine visual examples of multiplication and division using powers of 10. They also practice solving problems that their instructors model. If you are new to teaching these skills,...

Developing fluency with long division is a big step in the education of young mathematicians. With the support of base ten blocks, learners deepen their understanding of the operation in this elementary math lesson. Although it indicates...

Why doesn't dividing by zero result in infinity? Scholars view an engaging TED-Ed video that describes why division by zero is not allowed. It explains how division is related to the multiplicative inverse, and why 1/0 cannot be equal to...
