Learning Ratios and Proportions Through Scale Drawings

Proportions are ratios found using multiplication or division. Middle schoolers solve measurement problems, find a figure's missing dimension, and find the distance between two points. Resource features four lesson plans with detailed...

Real-life math is really great! In groups, learners measure objects in the classroom. After comparing measurements, they determine a scale and create a blueprint of the classroom. They discuss the purpose of using scale drawings in...

Scale drawings are an easy and plausible way to represent large things, such as roads and buildings, on paper. This tutorial explains what a scale drawing is and uses the example of a house to demonstrate how a scale drawing works. It...

Have your aspiring contractors compute the length of two walls in a compound-shaped attic when given a scale drawing of it and the other dimensions. They find the area, determine the number of rolls of insulation they will need to...

Give your future household repair specialists a real-life chance to apply the concepts of ratio and proportion. Using a scale drawing, they calculate the missing dimensions of two walls of a compound-shaped attic. They then figure how...

Using a scale drawing with some dimensions missing, aspiring do-it-yourself homeowners calculate the remaining sides of a compound-shaped room. They apply the principles of ratio and proportion to determine how much crown molding will be...

This sample notebook page walks you through the process used to create a scale drawing, which is a drawing where the dimensions are proportional to the actual size of the object being drawn in a predetermined ratio. This site provides...

Investigate the use of ratios in scale drawings. Learners scale objects up or down using ratios then find the actual size of something using ratios. They apply their knowledge of ratios as they make their own telescopes in science class....

Young mathematicians practice measuring acurately with a protractor. They convert measurements using a scale factor, then translate the new information into diagrams. This activity should be a hit in that it's mostly hands-on work with...
