# Math Empowers 4

## Fraction Equivalence and Ordering

Standard: 4.NF.A - Extend understanding of fraction equivalence and ordering.

Don’t forget that a Fraction Tower Classroom Basics Kit is useful to demonstrate equivalency and ordering of fractions! They are a great hands-on tool for teachers and for students.

Here are some great games to play…

¨ Equivalent Fractions – Illuminations game to create equivalent fractions by dividing and shading squares or circles, and match each fraction to its location on the number line.

¨ Dirt Bike Game: Comparing Fractions - A multi player tug of war game for comparing fractions.

¨ Comparing Fractions – Click on the symbol to compare fractions.

¨ Fraction Splat – Click on the target fractions.

Standard: 4.NF.B - Build fractions from unit fractions.

When adding and subtracting fractions, students should understand that a fraction (with a numerator greater than 1) is made up of unit fractions, e.g. 3/7 = 1/7 + 1/7 + 1/7. Remember to show that addition and subtraction of fractions is joining and separating parts referring to the same whole.

Here are some great games to play ...

¨ FractONE – A game where students click on sums of one.

¨ Fraction Game – An Illuminations activity where students work with relationships among fractions and ways of combining fractions on a number line.

## 100th Day of School

## Ideal Math Lesson vs. Workshop Model

The Ideal Math Lesson has four main components:

- Engage/Explore where the teacher guides the students through a discovery of the lesson,
- Explain/Elaborate where students complete their formative assessment,
- Differentiation based on the assessment, which can consist of centers or stations, and
- Evaluate where the lesson is summed up and reflected upon.
