Introduction to Decimals
Three activities make up an introductory lesson designed to create a strong foundation in comparing fractions to decimals and exploring and building decimal models. Pupils brainstorm and complete a Venn diagram to show how decimals and...

Adding and Subtracting Fractions
Fifth graders put their fraction knowledge to work by reading word problems and deciding whether to add or subtract the given fractions. Terms such as combined, total, difference, and left indicate which operation to use.

Identifying Fraction Location Positive and Negative
Sixth graders practice their fraction and number line skills by identifying where a given fraction is located on the line. Provide mathematicians with a colored pencil for easy identification of the fraction.
Common Core Sheets
Fraction Location on Number Line
Once your class has mastered the identification of fractions, have them locate fractions on a number line. This sheet reinforces interval sizes of parts included in a whole, and directly relates to the standards associated with Common...

Finding Ending Time with a Numberline
Third graders determine the end time on a number line, given the start time and elapsed time.
Common Core Sheets
Finding Elapsed Time with a Numberline
Third graders find the elapsed time on a number line, given the start and end times.
Common Core Sheets
Finding Start Time with a Numberline
Third graders determine the start time on a number line, given the elapsed time and end time.
Common Core Sheets
Finding Elapsed Time
Third graders read word problems to determine the elapsed time, given the start and end time.
Common Core Sheets
Finding Starting Time
Third graders read word problems to determine the start time, given the elapsed time and end time.
Common Core Sheets
Reading an Analog Clock (1 Minute Increments)
Third graders read analog clocks and tell time to the nearest minute. AM and PM do not matter in this exercise.
Common Core Sheets
Identifying Time Phrases
Quarter to seven. Noon. Five after three. These are a few examples of the time phrases students must identify. Most of the times to not indicate AM or PM; however, noon and midnight should be identified appropriately.
Common Core Sheets
Reading an Analog Clock (5 Minute Increments)
Second and third graders practice reading analog clocks to the nearest five minutes.
Common Core Sheets
Creating Area and Perimeter Rectangles
Third graders are challenged to draw their own rectangles given a specific area or perimeter. There are no examples of how each rectangle should look, so it is important for learners to persevere in finding a solution. There is more than...
Common Core Sheets
Rectangles - Same Perimeter and Different Area
Given a rectangle with specified dimensions, learners are prompted to create a new rectangle with the same perimeter, but a different area. This challenges third graders to think about perimeter and area in a new way. Each problem...
Common Core Sheets
Rectangles - Same Area and Different Perimeter
Given a rectangle with specified dimensions, third graders are prompted to create a new rectangle with the same area, but a different perimeter. This challenges learners to think about perimeter and area in a new way. Use activity as a...
Common Core Sheets
Determining Area with Partial Blocks
A more challenging set of worksheets, third graders are required to measure area by counting whole and partial unit squares. Students will realize that two partial blocks make up one whole block. Each shaded figure is on a square unit grid.
Common Core Sheets
Determining Rectilinear Area
Third graders find the area of rectilinear shapes by partitioning them into two non-overlapping rectangles and adding the areas of the non-overlapping parts together. It allows learners to recognize area as an additive.
Common Core Sheets
Determining Area with Full Blocks
Third graders simply count the square units that make up each figure in order to find the area. Remind the class to count carefully in order to find the correct answer.
Common Core Sheets
Determining Area with Square Units
Third graders measure area by counting unit squares inside a rectangle.
Common Core Sheets
Finding Area by Tiling
Third graders find area by tiling a rectangle based on the given side lengths. This helps learners visualize and create the area of a figure. From here, they can count the total number of tiles inside the rectangle to find the answer.
Common Core Sheets
Determining Perimeter with Square Units
Third graders determine the perimeter of a shaded section by counting the number of unit squares that surround it. Each section is shaded on a small square unit grid.
Common Core Sheets
Finding Side Length (Given Area)
Area is the amount of space that takes up the inside of a figure. To find the area of a rectangle, one must multiply the length by the width. Here, third graders are challenged to find the missing side length, given the area.
Common Core Sheets
Finding Side Length (Given Perimeter)
Perimeter is the total distance around an object. One can find the perimeter of a rectangle or square by adding all four side lengths together. These worksheets require third graders to find the missing side length, given the perimeter...

What Is a Foot?
An in-class and at-home assignment, young math stars find and list items from home and school that they think are one foot in length. Once the list is made, provide everyone with rulers to measure and find the actual lengths of their items.
