Fourth grade learners are learning how to decompose fractions. We are learning about improper fractions and mixed numbers and how to show these on tape diagrams and number lines. Learners are learning how to manipulate fractions and break them apart to show their understanding of what fractions represent.
Pictures, models, number lines and tape diagrams are the best ways to show student understanding of fractions. They especially help to show improper and mixed number fractions. A common mistake learners make is forgetting the denominator is ALWAYS the amount of total pieces no matter how large the numerator.

Our focus this week is on equivalent fractions. We will be comparing fractions using greater than, less than, and equal to symbols. We are also allowing learners to draw models and number lines to represent fractions. Fourth graders need to draw upon their prior knowledge of fractions.
Equivalent Fractions- Equivalent fractions are different fractions that name the same number. Let's look at some more examples of equivalent fractions. Example 2. Two-thirds is equivalent to four-sixths. *Draw two stacking numberlines to help you compare fractions. Use a ruler to determine if the fractions are equal OR equivalent. Remember to draw your "tick" marks on the numberline as equal parts just as you do for a fraction model. Learners are reviewing fractions. We reviewed what we learned last year about fractions and we will be exploring equivalent fractions. We are also developing an understanding of fractional models and fractions on the numberline. Learners will also learn about the types of angles.
Fourth graders are testing their knowledge about area and perimeter this week. They are beginning their Unit on fractions. Specifically learners will review fractions and learn about equivalent fractions. We are also reviewing how to solve multi-step problems.
