Guided Notes
Key concepts students will learn:
- •
When estimating the sum of two fractions, visualize each fraction to determine if it is more or less than one-half.
- •
If you add two fractions together and each fraction is more than one-half, then the sum will be more than one whole.
- •
Estimating fractions can be done by dividing a shape into equal sections to represent the denominator and shading in sections to represent the numerator.
