Explore multiplication and division using real life problems, including how to find the cost of soap per bar. Individuals or small groups work to find answers. They then share with the class how they found their answer.

In a math or life science class, "mini-me" models are created with cardstock to reflect a 1:10 scale of students' bodies. Learners measure each others' heights with meter sticks, and then reduce the size by 10. After this exercise, they...

Students explore their counting skills. In this counting lesson, students group objects in sets of 10 to practice counting them. Students also practice graphing the sets of objects they count.  This lesson incorporates the...

Explore multiplication through caterpillar study. Learners will view a caterpillar video clip and work with a group to determine how much they would weigh if they grew to be 3,000 times their size as does the caterpillar. They will...

Your learners use many different number representations like positive and negative integers, exponents, radicals, and combinations of operations as they learn and strengthen their use of the order of operations. Thoughtfully organized to...

Third graders explore their multiplication skills. They will use their problem solving skills to solve an everyday math problem that requires them to multiply numbers. This lesson incorporates the use a video titled "Blossom and Snappy...

Middle schoolers redesign their school to make it more energy efficient, and create a model of their design. Learners get together in groups of 5, and they take on the task of making their school more energy efficient. To do this, they...

Lower graders sort and group objects by their different properties. They watch a video about sorting then, sort and organize candy in different groups. Students compare how others sorted their candy. Finally, they decide which group has...

Learners construct their understanding of measurement and dimensions in this step-by-step approach that begins with an all group vocabulary introduction, consisting of measuring objects and dialoging using measurement vocabulary....

Two vehicles move at a constant rate of speed toward each other, but when exactly will they pass? Pupils use still images from a video to determine the rate of speed and when the two cars meet. Then, they watch the complete video to...

Graduation ceremonies are huge milestones, but sometimes waiting for a name to be called gets a bit boring. Scholars find the pace the announcer calls names to determine how long until a specific name is called. Calculations work in...

Earthquakes can be frightening and dangerous, but being prepared can make a world of difference. Perform an earthquake simulation during which the class practices how to drop, cover, and hold on as you read a script...

One thing that puzzles a lot of young algebrists is the factors in a word problem that are taken as "understood". This presentation on solving systems of linear inequalities does a great job walking the learner through how to tease those...

Your geometry learners use their knowledge of various geometric concepts to write proofs. Starting with givens containing parallel line segments with transversals and triangles and quadrilaterals, and the mid-point and distance formulas;...

How quickly does light travel long distances? A short video simulates light going from the earth to the moon at two different paces. Scholars relate the distance to the rate to understand which simulation is correct.

Students practice counting and comparing objects.  For this math lesson, students view a Count on It! episode. Students examine the value of what they are counting.  Students estimate number in groups of items.  Students...

Fourth graders compare amounts of time in seconds, minutes and hours.  In this multiplying and comparing time lesson, 4th graders problem solve a plumbing problem scenario to find which amount of time is the least.  Students...

First graders evaluate math problems using farm animals.  In this consumer math lesson, 1st graders discover math problems which concern quantities of farm animals.  Students discover new strategies to help them analyze their...

Third graders practice the division concept.  In this dividing lesson, 3rd graders watch a video that gives a simple division word problem. Students work collaboratively to find the solution.

Fourth graders explore their multiplication skills. In this number sense lesson, students use their problem solving skills to solve a word problem that requires them to multiply 2 or 3-digit numbers by 1 or 2-digit numbers....

Learners explore linear measurement. They choose appropriate measuring tools, measure three classroom items, and record their results.  A class discussion ensues in which everyone decides the best way to present their data.

Get second graders outside to estimate and measure how long 800 meters is on their school campus. They then measure the actual distance in yards to see how close their estimate was. An interesting teaching idea!

A presentation tool to record written text and pictures with audio voice-over and share privately or publicly online.

Winogradsky columns are ideal for observing the role of bacteria and other microorganisms in an ecosystem. This student activity guide is complete with data tables for observations and analysis questions for processing what was observed....
