Third grade is the year of multiplication. Though it was most likely introduced to kids in second grade, third grade is when kids are tasked with mastering their times tables and developing a stronger understanding of this key operation. This guided lesson in understanding multiplication can help give third graders a leg up. For even more practice, consider downloading the recommended multiplication worksheets that accompany the lesson.
This resource will help assess your students' mastery of concepts surrounding measurement and time. This worksheet will challenge your third graders with problems on area, perimeter, measurement, and elapsed time problems.
This summer-themed workbook prepares students to enter the fourth grade with the skills they’ll need, and includes practice with the core subjects of word study, math, reading and writing.
Fractions can be challenging when taught in an abstract way. That’s why this unit invites learners to engage with fractions and mixed numbers in very visual and concrete ways using number lines, tape diagrams and area models. Students will learn different strategies to practice identifying and generating equivalent fractions.
Fourth graders will discover the building blocks of geometry in this unit: points, lines, line segments and rays. Students will explore the properties of different shapes, including symmetry, parallel and perpendicular lines, and 900 angles. Students will apply their understanding as they learn to sort shapes based on these properties.
Week 4 of our Fourth Grade Fall Review Packet features five more days of diverse learning activities designed to prepare students for their fourth grade year.
Use this exercise with your students to build a foundational understanding of geometry. They will determine the area of shapes by counting the unit squares.
This workbook will challenge your fourth grader with math formulas, shapes practice and angle activities. Kids will also learn how to find areas and perimeters, classify triangles and calculate time.
Help learners gear up for a new year with this Fifth Grade Fall Review Packet - Week 3, complete with 5 days of activities in math, reading, writing, science, and social studies.
This workbook deals with more advanced forms of measurement, including pre-geometry concepts like perimeter and area, and data skills like graphing and charting.
Geometry in third grade introduces kids to the idea that shapes have different categories (rectangles, rhombuses, etc..) attributes (four-sided, etc...) and areas of different values. This lesson, designed by our curriculum experts, provides the guided instruction and practice that third graders need to conceptualize shapes in a deeper way. For more practice, download and print the third grade geometry worksheets recommended as part of this lesson.
What could be scarier than math practice? Make magic brew, juggle negative numbers, interpret multiplication cards, find the area of your dungeon and more!
Area is a geometric value that tells the size of a surface, and it is an important geometric concept that is commonly taught starting in third grade. Calculating the area of an object requires addition and multiplication skills, so after your student has mastered those concepts, you can help them move on to our worksheet resources for more practice in calculating area of different shapes.
Learn More About Area
The area of a shape is the size of the shape’s surface. An easy way to think about area is to think about how much paint you would need to cover the entire shape. There are a lot of different ways to calculate the area of a shape, so we’ve put together a guide to help you help your child get a head start on calculating area!
Area of Simple Shapes
Simple shapes, like squares, triangles, rectangles, etc. have specific formulas that you can use:
Square: area = length2
Rectangle: area = length × width
Triangle: area = ½base × height
Circle: area = π × radius2
Area by Counting Squares
Another way to calculate the area of a simple shape is to count up how many squares make up the shape if you put it on a grid. There are a couple ways to go about this way of approximating area:
More than half of a square counts as one full square and less than half a square counts as zero squares
Combine partial parts of squares to count as half a square or a full square.
Area of Difficult Shapes
Sometimes the shapes you work with aren’t simple shapes like rectangles or triangles. However, these difficult shapes will be made up of a combination of simple shapes (e.g., a triangle on top of a square). To calculate the area of these shapes, calculate the individual areas of the simple shapes and add them together to get the total area.
