Adding and subtracting mixed numbers need the same attention that regular fractions do by finding a common denominator. If you plan to use a vertical line-up of the fractions then this video is for you. It just introduces this method, it...

Middle schoolers identify proper, improper fractions, and mixed numbers.  They reduce fractions to their lowest terms. They add and subtract fractions with different denominators, and multiply and divide fractions, as well as...

Young mathematicians piece together the puzzle of fractions. Starting with the addition and subtraction of fractions with like denominators, this series of example problems and skills practice exercises transitions students...

Working with fractions that have unequal denominators is one of the most difficult concepts for young mathematicians to master. Here you will find a fine instructional activity that should help youngsters begin to get a grasp on...

Using a real-world example, this problem illustrates the thought process that learners need to engage in to understand adding mixed numbers with common denominators. First by looking at estimation, and then by drawing models that...

Using boats along in the Port of Albany as the focus, learners practice adding single-digit numbers and interpreting data. This lesson comes with the worksheets, resource links, and other materials to make it a worthwhile experience.

Have fun while building the number sense of young mathematicians with this list of ten-frame learning games. From developing cardinality and counting skills to learning place value and basic addition strategies, ten-frames are excellent...

Here is one of the better lessons I've come across on how to teach fractions and decimals. This lesson does a great job of showing how these two mathematical representations of numbers are interrelated. Some excellent websites, printable...

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...

Weighted averages can be tricky to explain! However, this study guide makes it easy for teachers by including definitions, explanations, and breaking down problems into three steps. Includes mixture problems and uniform motion problems.

Using the Hudson River as the focus, learners discuss the difference between salt water and fresh water environments, analyze maps and graphs, and complete addition and subtraction problems. This lesson comes with a wealth of...
