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...

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 lesson that should help youngsters begin to get a grasp on this important...

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...

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...

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...

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...

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.

Turn your class loose to experiment with the different fat content in skim milk, whole milk, half and half, and heavy cream. This is a visually vibrant experiment, as learners drip food coloring on the surface of the products and measure...

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 activity comes with a wealth of...

Elevate your fifth graders' understanding of math concepts with a series of vocabulary posters. Featuring terms concerning probability and statistics, measurement, algebra, and decimal place value (and many more), the posters are...

Get your class out in the environment for hands on math activities. For this wetlands lesson, learners transplant native plants, calculate how much soil is needed, and perform math activities based on this experience. They then make...

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