Halving is not always so simple. Small groups build a cube and then determine how to construct a cube that is half the size. Groups create two cubes, one that is the correct size and another that would be an alternative solution. To...

Build on your learners' confidence in quick addition as they discover strategies to add tens to two-digit numbers. After reviewing counting by 10's, they discuss tactics to add multiples of 10 to other numbers. They visualize how to...

Middle schoolers work in small groups to make various geometric solids with Play-Doh. They use fishing line to make cuts and observe the shapes of the cross-sections. Pupils complete an assessment in which they answer questions such as:...

Geometry.... sweet! Using sugar cubes, learners build rectangular prisms of different sizes and shapes. They glue them together and assess volume. Then they color the outer sides to visualize and compute surface area. To make a visceral...

Math class is full of drama—there are so many problems to work out! Pupils work out factoring problems. They use quadratic methods of factoring higher degree polynomials, in addition to factoring the sum and difference of two...

Examine patterns of figures composed of six-squares and predict which of the twenty presented could be folded to make a cube. They then fold large-scale patterns of these figures to confirm their hunches.

Predict outcomes using linear models. Young mathematicians strengthen their understanding of slope and linear models using a hands-on activity. They monitor the dissolving rate of bouillon cubes, graph their data, and make predictions...

Learners calculate volume using the correct formula and the correct unit. They explore different prisms, spheres, cubes, and cones as they calculate volume and relate it to depths in oceans.

Show learners how to develop a procedure for solving equations using radicals with the fifth lesson of the 25-part module that challenges learners to use properties to solve multi-step quadratic and cubic equations. Individuals round out...

An 80-page resource provides four lessons and all associated worksheets to teach middle schoolers about expressions and equations. The lessons are hands-on, using games, "integer chips," a balance and cubes, and cut and paste activities....

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

Fifth graders investigate geometric shapes. In this geometry lesson plan, 5th graders classify and group shapes and patterns by likeness. They investigate patterns based on clues from their peers.

Tenth graders investigate volume in class and in the real world. They explore volume of cylinders and prisms as it relates to different subjects. Pupils also investigate how important volume is in different career field.

High schoolers investigate the concept of diffusion and how materials enter and leave a cell. In this movement across a membrane lesson plan, students use perfume, food coloring in water and a sugar cube in water to observe diffusion....

Students define area and perimeter. They demonstrate understanding of the concepts concretely, with manipulatives, and describe with words, their strategies and thought processes.

Students investigate finite mathematics using a flow chart. In this algebra lesson, students investigate logic and strategies using flowcharts. Students compete against each other using different approaches to playing the game.

Fourth graders examine how to determine the probabilities or likelihood of outcomes. They complete trials to determine probability while using different manipulatives. They determine how games can be made fair or unfair in this unit of...

How do graphic designers project three-dimensional images onto two-dimensional spaces? Scholars connect their learning of matrix transformations to graphic design. They understand how to apply matrix transformations to make...

Introduce young mathematicians to concepts of financial literacy with this open-ended word problem. With seven dollars to spend during field day and given a list of available items and their prices, children must determine how they want...

Students listen to "Heat Wave" by Helen Ketterman and discuss the story by creating a word web with heat as the main topic. They break into groups and conduct an experiment using a thermometer to record the temperature of melting ice...

Students practice collecting and graphing data using interlocking cubes. In this graphing lesson, partners count cubes and graph them. They also use a meter stick to measure arm span and height then compare the results with the class as...
