Students explore the primary function of the respiratory system in multiple activities. In this respiratory system lesson, students build a model of the respiratory system to investigate how the lungs work.

This lesson engages learners in a variety of activities to build 1 to 1 correspondence, estimation, and problem solving skills. They discuss problem solving strategies, hear the story Ten Flashing Fireflies, compose their own word...

Young mathematicians listen to the book Sold!: A Mathematics Adventure by Nathan Zimelman where they encounter ways to solve story problems. They then create and solve start unknown addition and subtraction equations. Resource builds in...

Young learners practice addition and subtraction to solve problems. They use a webquest application to model how to solve math problems using pictures, words and numbers, and also practice using multiplication and division.

This thorough introduction to the concept of subtracting negative integers walk learners through the necessary steps using teacher modeling and guided practice. Number lines and various word problems are used to support understanding of...

Second graders examine the relationship between addition and subtraction. In this number sense lesson, 2nd graders practice their computation skills and use various strategies (including manipulatives and calculators)  to...

Second graders explore estimation and place value. For this place value lesson, 2nd graders estimate and construct numbers while working with spider activities. Students use addition and subtraction to compare estimates. Resources and...

In this visual expressions worksheet, 8th graders solve 10 different problems that use visual expressions to solve. First, they write the numerical expression for the models illustrated. Then, students use a number line to solve two...

Fifth graders estimate their results and then prove through calculations. In this math lesson, 5th graders solve problems using multiplication, division, addition, and subtraction. They also use mental math to solve their problems.

Third graders explore the attributes of 3-dimensional shapes. In this shapes lesson, 3rd graders examine faces, edges, and vertices of 3-dimensional shapes as they construct shapes using marshmallows and toothpicks.

Students engage in an interesting lesson on addition that encourages class participation through role-play and concrete hands-on activity. They utilize the fact that ladybugs have dots on their bodies to create a fun, hands-on lesson in...

For this order of operations (i.e., addition, subtraction, multiplication, division) worksheet, middle schoolers solve 4 word problems demonstrating their understanding of the concept.

Fourth graders estimate various measurements. In this lesson on measurement, 4th graders estimate the length and mass of multiple objects. Students discuss the difference between a guess and a reasonable estimate and discuss using...

Ninth graders graph linear equations and inequalities in two variables and then, they write equations of lines and find and use the slope and y-intercept of lines. They use linear equations to model real data and define to define the...

First graders practice modeling addition. In this hands-on addition lesson plan, 1st graders are introduced to the Commutative Property of Addition and the Zero Property of Addition through modeling and the use of manipulatives. This...

Guide your young mathematicians through an exercise in composing and decomposing numbers from 0 to 10. The prompts ask learners to match an addition sentence to the model, to select which of the equations makes 9, and which one makes 6....

Understanding arrays is very similar to understanding the relationship between multiplication and area. Give your third graders an opportunity to practice identifying area models that relate repeated addition and multiplication. They...

Your learners combine their knowledge of real and imaginary numbers and matrices in an activity containing thirty lessons, two assessments (mid-module and end module), and their corresponding rubrics. Centered on complex numbers and...

I like algebra, but graphing is where I draw the line! Worksheet includes three multiple-part questions on interpreting and drawing line graphs. It focuses on the abstract where neither axis has numbers written in, though both are...

MAD about statistics? In the seventh chapter of an eight-part seventh-grade workbook series, learners develop probability models and use statistics to draw inferences. In addition, learners play games and conduct experiments to determine...

In this real-world problem about the rapid growth of rabbit populations, students must analyze two different scenarios and create mathematical models to represent them. They use their exponential models to answer questions about the...

Budding mathematicians investigate how to write number sentences using the Roll-the-Dice tool in "Kid Pix". They correlate the dots on the dice to numbers and then learn to use the addition and equal symbols to write number sentences....

Model the effects of practice on texting speed. Pupils develop a linear equation that models the change in texting speed based on the amount of practice. The sixth performance task in an eight-part series requires learners to solve...

This study guide would be great to use when presenting a lesson on ratios and proportions. It includes clear definitions, explanations, and examples to work through as a class or individually. In addition, it has notes on rates and...
