Fantastic Fractions
Fourth graders work with fractions using hands on experiences and reasoning skills and use fractions to communicate the idea of a part of a whole.
Curated OER
Tetrominoes Cover-Up
Third graders compare and contrast the attributes of two-dimensional shapes. Using a tetrominoes game, they create two-dimensional shapes to cover up a game board. At the conclusion of the game, 3rd graders discuss the patterns they...
Curated OER
Fantastic Fractions
Fourth graders explore and examine through hands-on experience and reasoning the concept of fractions. They solve problems involving multiplication and division of whole numbers and addition and subtraction of simple fractions and decimals.
Curated OER
Ball Toss Activity
Pupils collect data from tossing a ball into the air. Using a data collection device, they graph the data, set a window, and analyze the height of the toss, how long the ball was in the air, etc. They then find an equation that models...
Curated OER
Angle Land and Angle Aerobics
Sixth graders investigate different types of angles. In this geometry lesson, 6th graders use a protractor to identify acute, obtuse, and straight angles.

Mathematics-Algebra II
Tenth graders investigate relations and functions. In this algebra lesson, 10th graders perform or research real life situation involving functions. This assignment can be used as a year end project.
Curated OER
Cars in Garages
First graders investigate whole numbers, and how numbers are often made up of smaller numbers. They determine the underlying concepts of addition and subtraction by examining how there is a finite set of number pairs for a given number....
Curated OER
A Square of Circles
Second graders practice calculations and working with even and odd numbers. They perform mental calculations involving addition. Students devise and use problem solving strategies to solve problems.
Curated OER
Shaking Hands
Students use diagrams or lists to show relationships. They also identify the pattern of triangular numbers. The mathematics behind situations provide a way of problem solving to examine the answers.
Curated OER
Buttons and Bears
Students read the problem and then identify the important information in the problem and highlight. They then brainstorm for ways to solve the problem by drawing a picture and working in pairs.
Curated OER
The Fathers' Day Card
Students subtract using decimals and find half of a decimal number. They write and solve problems which involve decimals and which require a choice of one or more of the four arithmetic operations.
