Mathematics of Scale

Develop scales using tables. Pupils complete charts to show equivalent scale factors before using the completed tables to determine the sizes of scale drawings. They finish the lesson and demonstrate their understanding by completing a...

The original drawing is eight units — how big is the scale drawing? Classmates determine the scale percent between a scale drawing and an object to calculate the length of a portion of the object. They use the percent equation to find...

Calculate the areas of scale drawings until a more efficient method emerges. Pupils find the relationship between the scale factor of a scale drawing and the scale of the areas. They determine the scale of the areas is the square of the...

Class members take scale drawings and examine scales to determine distances in the actual objects. Pupils convert the scales of different units to scale factors that can be used in proportional equations.

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...

Sixth graders examine a blue print and discuss the reasoning behind using blue prints. For this proportionality lesson,  students collaborate with their teammates to create a scale drawing. Once that is complete, 6th graders write a...

Middle and high schoolers explore the concept of scale drawings. They discuss what a scale is and that scales provide a ratio. Pupils construct a scale drawing of their classroom using graph paper.

Learners explore scale drawings. They use maps to investigate scale drawings.  Students create a scale drawing of their own island. 

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...
