Using Scale

It's a neat idea, but the task of designing a system for filling jars with consistent specific amounts of a product may be a little out of reach, especially for younger pupils. Intended as an engineering design lesson, this may be better...

Just how big would it really be? Young mathematicians determine if different toys are proportional and if their scale is accurate. They solve problems relating scale along with volume and surface area using manipulatives. The last day of...

Scale up your lessons on geometry and ask learners to investigate conditions on triangles, scale drawings, area and circumference of circles, and angle relationships. The resource includes activities and a homework assignment.

Teach the basics of measurement and conversion with a five-lesson resource that builds an understanding of proportion and measurement conversion from elementary through high school. Initially, young scholars use ratios to determine soup...

To take the longest path, go around—or was that go over? Class members measure scale drawings of a cylindrical vase to find the height and diameter. They calculate the actual height and circumference and determine which is larger.  

If members of your class wonder where they can use the math they learn in middle school, let them discover the answer. Learners apply geometry concepts of scale and measure to calculate the costs of framing a house addition.

See how design and geometry go hand in hand. The activity asks learners to use geometry to design a backyard garden given dimensions of each feature. Scholars work with ratios and scale to develop an accurate scale drawing that includes...

Create a class quilt in this geometry lesson. Learners measure and cut out polygons from felt or graph paper and put the squares together to form a class quilt.  They need to use knowledge of fractions, scale, polygons, and area to...

Everyone loves a sale, but they need to know how to find the new price with the scale factor and proportions. The scale factor is like the key needed to find that missing piece of the puzzle. Show your learners how to find the scale...

In a math or life science class, "mini-me" models are created with cardstock to reflect a 1:10 scale of students' bodies. Learners measure each others' heights with meter sticks, and then reduce the size by 10. After this exercise, they...
