Learners find the proper factors for numbers one through fifty using either the divisibility laws or TI-82. They determine the sum of the proper factors for each number. If the sum of the factors is less than the number itself, then this...

Fifth graders become familiar with problem solving strategies of guess and check and working backwards. They demonstrate the basic concepts of addition, subtraction, multiplication, and division using a math sentence.

Students investigate concepts related to data collection and interpretation. They generate all possible outcomes in a beginning study in the realm of statistics. The use of real life situations helps to engage students.

Students make estimates and then measure leaves for accuracy. They calculate the area of the leaves by drawing an outline on graph paper and counting the squares. They compare the leaves exposed to sunlight to those that are in constant...

Pupils perform an activity in small groups in order to investigate different types of shapes found in photographs taken with a digital camera. The integration of technology is used to engage students in the lesson.

In this math worksheet, students are given examples of different memory capabilities for the types of storage devices. They match the memory to the device for fifteen problems.

Four is the perfect number—if you're talking about parallelograms. Scholars determine a possible fourth vertex of a parallelogram in the coordinate plane given the coordinates of three vertices. They read a conversation...

Three heads are better than one. After reading a conversation between three friends about how to compare fractions, scholars analyze and discuss each presented strategy. These include using unit fractions, using benchmark fractions,...

Could you develop your own way to add fractions with unlike denominators? An in-depth task has scholars examine a fictional conversation between several people in which they discuss a method of adding fractions with unlike denominators....

Math and M&Ms® go great together when introducing a modeling activity. Allow your learners to simulate population growth and decay of fish in a pond and share their reasoning for the change in fish. With such an impact we have on our...

How much can a cat eat? The five-question fraction assessment asks pupils to determine the fractional portion of a food box eaten by cats. Learners show their proficiency in adding and subtracting fractions using several scenarios...

New Horizons began its journey to Pluto in 2006. Ten years later, it continues its mission. In that time, scholars have surely grown, but how much more will they grow by the time New Horizons reaches its destination? Find out with an...

Teach the basics of measurement and conversion with a five-lesson resource that builds an understanding of proportion and measurement conversion from elementary through high school. Initially, young scholars use ratios to determine soup...

Make the cookies healthy. The assessment task asks pupils to determine the number of cookies they could make based on a given amount of ingredients. Given two sugar substitutes, learners determine which substitute would be better and...

Reduce the pressure in the classroom. The second instructional activity in an Airplanes unit of 22 introduces the class to Bernoulli's Principle. Pupils demonstrate the principle by blowing between different objects causing a reduction...

With instructions to adapt the activities for any grade K-12, any teacher can incorporate the concept of scale into the classroom with a simple, yet effective lesson.

There's no need to stay inside; get out of the classroom and create a scaled map of the solar system on your playground field! In collaborative groups, scholars identify the distance between the sun and other planets, place planet...

Fall back and slow down. The fourth lesson in a six-part series on air traffic control leads the class to find the difference in distance traveled based upon the difference in speed. Pupils work through a problem related to walking...

Split the work three ways. Learners use their knowledge of fractions to solve problems dealing with splitting up work loads evenly between three groups. Scholars determine the fractional portion of work each group will do along with...

This presentation covers a lot of ground. Square numbers, metal math computations, commutative property, ordering positive and negative integers, factoring, and real world problem solving are all covered. Use over the course of several...

Humans have been developing number systems for thousands of years, and while they can be very different from one another, they can also share surprising similarities. Take your young mathematicians on a journey through the history...

Find examples of math properties! On each of these two worksheets, learners examine five sets of number sentences, marking the ones which demonstrate the indicated property. The first page deals with the associative property. For...

The distributive property is a foundational skill taught two ways in this interactive web page. Your young mathematicians can practice their order of operations by solving distributive problems working from inside out. They then move on...
