Cutting shapes into equal parts
Description
Exercise Name: Cutting shapes into equal parts
Math Missions: 3rd grade (U.S.) Math Mission
Types of Problems: 1

The Cutting shapes into equal parts exercise appears under the 3rd grade (U.S.) Math Mission. This exercise connects the arithmetic idea of fractions with the geometric concept of part of a whole.

Types of Problems

There are is one type of problem in this exercise:

1. Tell the amount shaded: This problem describes a situation and draws a picture. The user is asked to fill in the amount of the shape that is shaded as a fraction.

Strategies

This exercise is easy to get both accuracy and speed badges. The problems are simple and the numbers are small.

1. The fraction numerators are always 1.
2. The fraction denominators in research never exceed 4, so the answers are either ${\frac{1}{2}}$, ${\frac{1}{3}}$ or ${\frac{1}{4}}$ each time.
3. Looking at the diagram is generally faster than reading the problem, but the point is to connect the two concepts together.

Real-life Applications

1. Fractions appear in every-day media to display information to consumers.
2. Fractions are used in real life in lots of different ways, but are commonly used in cooking, construction and science.
3. The ancient Egyptians from over 4000 years ago were very good at shapes and geometry. Every time the Nile burst its banks and flooded the planes, they had to use geometry to measure their gardens and fields all over again.
4. Architects use shapes to construct houses and skyscrapers
