Pupils will analyze scales as related to models and real life in this geometry lesson. They work together to compare the dimensions on a model as compared to the real building.

In this similar polygons worksheet, students identify the corresponding sides of polygons.  They use proportions to solve problems.  Students determine the scale factor of similar figures.  This two-page worksheet contains...

Sixth graders investigate scale models of toys.  In this scale models of toys activity, 6th graders bring in toys from home to measure.  Students discuss scale and what scale is used with their toys.  Students determine...

Middle schoolers are introduced to a problem involving an environmental issue. They are introduced to the capture-recapture method which involves capturing fish, tagging them, returning them and recapturing another sample. Pupils work...

students are the opportunity to enhance their computation skills using real life statistics associated with the Space Shuttle. Skills emphasized include working with fractions, decimals, percents, ratios and proportions, comparing units,...

Eighth graders follow a recipe, focusing on the concepts of ratio and proportion, to mix a batch of icing. They decorate cupcakes in the form of a pumpkin.

Middle schoolers identify and interpret various ways of expressing probability as a decimal, fraction, percent, or ratio. They solve problems based on probability as they apply to real world applications.

Learners use cross-multiplication to find the unknown respiration rate of an astronaut. In this multiplication lesson plan, students also use the same process to find missing values in proportions.

Students examine folk’s tales for Cause and Effect. For this literature lesson, students read "The Origin of Fire" and "The Origin of Medicine” and look for cause and effect. They use a TI Navigator to write down their findings.

For this solving proportions using cross products practice worksheet, students sharpen their problem solving skills as they solve 6 story problems.

For this comparing ratios worksheet, students solve and complete 3 different problems using the screens shown. First, they write a ratio that compares the shaded part to unshaded part illustrated. Then, students use the same grid to...

Students determine the length and width of leaf samples to the nearest millimeter and the circumference of trees. They participate in a discussion about the importance of collecting specimens carefully. They compile accurate...

Students use the correct tool to measure distances. For this geometry lesson, students use an odometer and ruler correctly as they study maps. They describe how far way something is.

In this geometry worksheet, students identify the different ratios of triangles using the theorems. They use SSS, SAS, ASA and AAS to differentiate between triangles. There are 7 questions with an answer key.

Young scholars establish a strategy for adding simple fractions. They convert improper fractions to mixed numbers and interpret drawings and storyboards.

Your class will use a TI calculator to drag vertices of rectangles and triangles to observe what happens to ratios of pairs of sides within each figure. They will apply the definition of similarity to identify similar shapes. The...

Students select appropriate tools and technology to perform tests, collect data, and display data. They construct appropriate graphs from data and develop qualitative statements about the relationships between variables.

Mathematicians compare triangles at different scales. In this geometry lesson plan, high schoolers calculate the area and perimeter of triangles. They use the Ti to make observation of the change that takes place as the triangles are...

In this proportional ratios activity, 9th graders solve 10 different problems that include sets of fractions in each. First, they determine if the product of the means is equal to the product of the extremes. Then, students solve each to...

In this math worksheet, student compare the recipes for three different salads. Using the concepts of percents and proportions the amount of beans is calculated.
