Perimeter check! Pairs work on finding the areas of semicircles and quarter circles using a relationship with squares. The problems challenge pupils to find areas of composite figures made from rectangles, semicircles, and quarter circles.

Who knew that a party is all about the area. Individuals draw out a patio on grid paper while planning to host a party. Using colored paper to represent the total area of the patio, learners cut out furnishings to add to the patio,...

Although there are grammatical errors in these word problems, they provide a good opportunity for scholars to practice calculating area. Each of the 10 scenarios gives measurements of a specific rectangular space, including units....

Geometers find the area of four circles given their circumferences. Circumference is presented in the form of "numeral (diameter) x pi"; the answer key shows solutions as  "numeral (radius squared) x pi," so computation is...

In this area of triangles worksheet, students solve 18 area of triangles problems.  Students find the area of various types of triangles given a graph of the triangle.

In this area learning exercise, learners read and problem solve the area of 8 triangles. Students show their work on each problem on the learning exercise.

In this area of polygons activity, 9th graders solve two area of rectangles, one area of parallelogram, and ten area of triangles problems.  The formulas for finding the area of these figures are provided.

In this area worksheet, students solve 6 short answer problems. Students find the area of a figure composed of regular polygons such as triangles, rectangles, squares, etc given a sketch of the figure.

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...

Not all area word problems are straightforward. Here are some trickier ones to challenge your beginning geometers. They determine the area of two irregular shapes and one rectangle using given measurements. Remind scholars to use square...

Each of these rectangles and squares has the length and width given with units. Can scholars solve for the area? Designed for beginners to this skill, all of these are whole-number single-digit measurements. There is a detailed example...

Find the area; scholars examine nine images of squares and rectangles with width, length, and units provided for each. They multiply double-digit numbers to find the area, writing it into the box provided. Because square units are...

Scholars use formulas for the area of a circle and the area of a rectangle to determine the number of pies a baker can make from a particular area of dough. They must also take into account rolling the remaining dough into a new sheet.

A deceptively simple question setup leads to a number of attack methods and a surprisingly sophisticated solution set in this open-ended problem. Young geometers of different strengths can go about defining the solutions graphically,...

Trigonometry teachers often go off on a tangent, and here's a instructional activity that proves it! First, young mathematicians use a formula with tangent to prove a formula correct for area. Then, they draw conclusions about the area...

In this area of polygons worksheet, young scholars find the area of 12 polygons. Each shape is drawn on a grid. The area of each square on the grid is given. Problems are all multiple choice.

Students estimate the area of states using the formulas for the areas of rectangles, squares, and triangles. In this geometric shapes lesson, students divide irregular shaped states into shapes. They use the formulas for areas of...

There are 10 word problems here, all in the same format. Learners are presented with the geometric scenario of a rectangle divided into rows and columns. They must determine, based on the number of each, how many squares are inside the...

Middle and high schoolers construct a triangle using Cabri Jr. They construct squares on each of the legs and hypotenuse of the triangle. Pupils show that the area of the squares on the leg equal the area of the square on the hypotenuse.

Take young mathematicians on an exploration of the world of 3-D geometry with this seven-lesson unit. After first defining the terms perimeter, area, and volume and how they apply to the real world, students continue on...

Geometry novices will enjoy this approach to finding area, as they aren't required to include units or a formula. The main objective here is to segment a rectangle into columns and rows to create squares, which then are used to find the...

In the first of a two-day lesson on transformations with matrix notation the class transforms the unit square using general transformations, then calculates the area of the transformed image. They discover it is the same as finding...

Clever! Participants don square-foot cardboard shoes to mark out the rain garden plot that they have spent the last few weeks designing. In this way, they are practicing scale modeling as well! Note that this lesson is part of a unit,...

Engage young mathematicians in applying their knowledge of area and perimeter with a fun geometry activity. Through a series of problem solving exercises, children use their math knowledge to design different-sized garden...
