This hands-on lesson takes young geometers on a tour of 2D polygons and 3D polyhedrons. After exploring different web resources and discussing geometric shapes, small groups construct models of polyhedrons using bendable straws. Note:...

Study Fibonacci sequences and see a related set of numbers. Learn and review Lucas numbers and use of quadratic equations to find a general term of a sequence of numbers that is generated by a recurrence relation similar to Fibonacci's.

Youngsters count, classify, and estimate quantities using buttons after a read aloud of The Button Box by Margarette S. Reid. They discuss the difference between guessing and estimating. Based on an experiment, they predict the...

Shapes are so fun! Little ones explore, identify, and create shapes using tangrams or pattern blocks. The activity is intended to stimulate critical thinking while engaging learners through play and shape identification. Each child will...

Students participate in a series of hand-on, online, and multimedia activities to examine 2 dimensional and 3 dimensional shapes. They describe common geometric solids. They construct rectangular prisms using straws and ribbon.

Fourth graders engage in a lesson that is about the concept of rounding decimals. They review place value and focus it upon the practice of rounding. Students use 10 base decimal grids or models to help make connections with the skill.

Upper graders identify the surface area and attributes of figures that are measurable. They estimate, measure, and record perimeter, area, temperature change, and elapsed time, using a variety of strategies. They also determine the...

Students read The Greedy Triangle and discuss geometric solids. In this geometry lesson, students list the geo-solids in the world and create a graphic organizer to show where geo-solids exist.

Demonstrate several ways to represent data with your class. They will use surveys to gather data and display the data using tally charts and graphs. Then answer questions according to the data.

Upper elementary and middle schoolers answer ten mutliple choice questions by applying the formulas for finding the area, perimeter, and volume of a rectangular prism.

Put geometry skills to the test! Learners solve compound inequalities and then graph the inequalities on a coordinate plane using their geometric skills. They identify the slope and y-intercept in order to graph correctly. I like this...

Students measure using the metric system. In this geometry lesson, students solve problems using grams, meters and liters. They convert between the US units of measurements and the Metric System.

Students solve problems using the Pythagorean Theorem. In this geometry lesson, students identify the Pythagorean Triple and use it to solve real life problems.

This is an amazing 33-page resource for teaching multiplication! Your mathematicians will discover the connection between multiplication and repeated addition. They also will work collaboratively with arrays while studying zoo animals....

Investigate multiplication problem solving strategies by working with base 10 blocks. Learners decompose problems with a Merlin the Magician theme. Multiple resources are provided.

Develop multiplication skills with your class. Youngsters will visualize multiplication as repeated addition. Then they will create a multiplication bug book and discover arrays as a strategy for multiplication problem solving....

Scholars create and perform experiments attempting to answer Buffon's Coin problem. They discover the relationships between geometry and probability, empirical and theoretical probabilities, and area of a circle and square.

What happens to a volume when you scale the dimensions of a rectangular prism? In this problem, a box of clay is increased in each dimension, with the intent to see if learners can generalize the result. The addition of...

Everyone loves a lesson that involves throwing things around! To understand probability, your experimenters will predict how different cylinder-shaped objects will land when tossed. When the data is collected, they will calculate the...

The objective of this activity is to find the percent of the area of a two squares overlapping. Mathematicians find the ratio of area for the part that overlaps to the rectangle formed. The final answer is a percent as a rate per 100....

Learners demonstrate their knowledge pictorially, concretely, and abstractly in this unit meant to last three hours over three days. Using hands-on activities, manipulatives,  real-world applications, and problem...

Who can get to 100 first?! It may be in the hands of chance, but either way kids will have to practice counting and adding along the way. Partners take turns rolling two dice and moving their game pieces that many spaces until one pupils...

Applying this metric worksheet, mathematicians will provide standard metric units of measurement, identify the largest and best way to measure items using the metric system, and convert units using King Henry.

Young mathematicians look at five 3-D shapes and name them based on the accompanying image. For each shape, learners state the number of faces, vertices, and edges.
