Quickly get to the decimal point. The last assessment in a nine-part series requires scholars to work with decimals. Pupils compare the race times of several athletes and calculate how much they have improved over time. During the second...

Young mathematicians solve linear equations by drawing models of algebra tiles using colored pencils. To finish, they solve the same equations algebraically and check their answers using a graphing calculator.

Stuck trying to remember the formal language of a geometric proof? Never fear, this handout has them all ready to go. The reasons are sectioned by topic so this handy guide is ready when you are to tackle those two column proofs. 

Mathematics involves a study of patterns. The exploratory lesson has learners consider the addition pattern in different sets of numbers. Each set has a different pattern that pupils describe mathematically. The patterns involve...

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...

Aim high with a task on window washers. An assessment task challenges learners to determine the number of windows two people wash. They do this using a given number of window rows on each side of a building. In addition, they find the...

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...

There's more than one way to solve a math problem! Introduce your class to this concept with a reading passage. After reading, learners answer five related questions.

Can they put it all together? Ninth graders apply what they know about proofs and triangle congruence to complete these proofs. These proofs go beyond the basic triangle congruence proofs and use various properties, theorems, 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...

Double win with a comprehensive worksheet and an excellent worked out answer key. The worksheet itself is twelve pages and begins with the simple sine and cosine graphs, then, develops into the reciprocal trig functions. 

For this integers instructional activity, students solve and complete 4 different types of problems. First, they multiply a positive integer times a negative integer and write as a negative number. Then, students divide a negative...

Scholars find a pattern from a geometric sequence and write the formula for extending it. The worksheet includes a table to complete plus four analysis questions. It concludes with instructional implications for the teacher.

Sing a song, practice step by step and assess your knowledge on the properties of addition with this interactive lesson.

Score goals as you answer questions about the properties of addition.

The goal of this task is to help students understand the commutative property of addition by examining the addition facts for single digit numbers. Aligns with CCSS.Math.Content.3.OA.D.9 Identify arithmetic patterns, and explain them...

In this exercise, students practice repeated addition. Students receive immediate feedback and have the opportunity to get hints, watch a tutorial video, and try questions repeatedly.

The purpose of this task is to study some patterns in a small addition table. Aligns with CCSS.Math.Content.3.OA.D.9 Identify arithmetic patterns, and explain them using properties of operations.

What is the commutative property? Why not ask Lois. She knows all about math "lingo." A site where kids can find math definitions explained in "kid friendly" language.

Identify arithmetic patterns (including ones in the addition or multiplication tables), and explain them using properties of operations. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a...

After completing this tutorial, you'll know what a linear equation is and how to solve one using various arithmetic properties. Contains several definitions, problems with step-by-step solutions, and practice exercises. Includes links to...

This task builds on that knowledge by asking them to study more carefully the make-a-ten strategy that they should already know and use intuitively. Aligns with CCSS.Math.Content.3.OA.D.9 Identify arithmetic patterns, and explain them...

[Free Registration/Login may be required to access all resource tools.] The video describes how to determine which addition fact is related to the given addition problem. The video uses vocabulary of addends and sum. The video is...

Practice discovering and explaining patterns in multiplication tables. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints. CCSS.Math.Content.3.OA.D.9 Identify...
