Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This...

Break out those math manipulatives, it's time to teach about area! Capturing the engagement of young mathematicians, this three-lesson series supports children with learning how to measure the area of squares, rectangles, and other...

Looking for an estimation activity a bit more involved than the typical "guess the number of jellybeans in the jar" game? Here, learners use a picture to estimate the number of people at a large event, look for potential problems with...

Design your dream classroom. The lesson plan contains an exercise to have teams create a scale drawing of their dream classroom. Pairs take the measurements of their classroom and furniture and create a scale factor for them. To finish...

Use the handout as guided or independent practice in drawing a reflection of a rectangle over a line. Three rectangles are provided for practice in addition to a critical thinking question.

Students explore the volume and surface area of three dimensional figures. Through the use of video, students discover three dimensional shapes, their uses in real-life applications, and methods used to calculate their volume and surface...

Fourth graders use the story of the discovery of irrational numbers to explore the different classes of numbers, the different ways in which numbers may be represented, and how to classify different numbers into their particular class.

With minimal setup and maximum freedom, young geometers are encouraged to think outside the box on a seemingly simple application problem. Though the task seems simple, measuring a given paper clip and finding how many 10 meters can...

Sometimes simple is just better. A set of activities teaches young mathematicians about using plausible estimation to solve problems. They break problems down to simpler problems, use rounding and estimation strategies, and consider...

Seventh graders watch a video and enlarge and shrink scale by applying proportional thinking. They practice measuring, using percentages, computing area, and problem solving.

Fourth graders read an article, then search for verbs, adverbs, nouns, pronouns, etc. In groups, they exchange papers and try to guess what the other poem was about.

"Fore!" All right, no one really yells this out in miniature golf, but this well-defined activity will have your charges using lots of numbers in their unique design of a miniature golf hole. Included in the activity criteria is the...

First graders explore the existence of patterns in everyday items. In this science and math integrated instructional activity, 1st graders match leaves with a name word card and organize them into four patterns. This instructional...

Take flight with a fun activity focused on graphing data on a coordinate plane. As learners study the data for Granny's hot-air balloon trip, including the time of day and the distance of the balloon from the ground, they practice...

Creative problem solving is fun and helps kids conceptualize content. They use grid paper, manilla paper, and markers to cut, draw, and show given double-digit numbers as many ways as they can.

Class members use the powers of multiplication in the 19th installment of the 32-part unit has individuals to utilize what they know about the multiplication of complex numbers to calculate the integral powers of a complex...

Sixth graders conduct a survey and collect data to construct a bar graph that will then be changed into a circle graph. With the bar graph, 6th graders compare estimated fractions and percentages and estimate percentages. With the circle...

Kindergarteners explore various representations and uses of numbers to develop number sense. They participate in an activity and arrange patterns into groups. Students compare the sets and describe the objects in each set.

Students investigate ratios of various objects.  In this ratios of various objects lesson, students draw pictures on graph paper and then dilate or shrink the image.  Students determine the ratio of their pictures. ...

Students explore geometry by participating in a school measuring activity. In this perimeter instructional activity, students discuss the techniques and methods used in order to measure a large perimeter or geometric figure. Students...

Students identify the different place values. In this algebra lesson, students represent decimal place values with manipulatives. They identify the correct place value using commas and mathematical reasoning.

Students explore how the Pythagorean Theorem works and how to apply it.

Students are introduced to the Pythagorean theorem. They use three different activities that give students the opportuntiy to observe triangles, and use the Pythagorean theorem and practice different ways of determining areas of...

Second graders collect data by spinning two spinners and creating sums, organize the data, and make conclusions from the data. Each students makes a spinner. They spin and record the number of the section each time. Students work in...
