In this unit we will:
- Model fractions of a whole quantity, length, shape, or object, in various ways, limited to denominators of 12 or less.
- Visualize fractions as compositions of a unit fraction.
- Identify the numerator and denominator of a fraction in various representations.
- Name a given fraction.
- Express fractions, including one whole, symbolically, limited to denominators of 12 or less.
- Relate various representations of the same fraction, limited to denominators of 12 or less.
- Compare the same fraction of different-sized wholes.
- Compare different fractions of the same whole that have the same denominator.
- Compare different fractions of the same whole that have the same numerator and different denominators.
- Express the relationship between two fractions of the same whole, using <<, >>,or ==.
- Relate a fraction less than one to its position on the number line, limited to denominators of 12 or less.
- Compare fractions to benchmarks of 0, one half, ,and 1.
We use fractions every day in many different situations. Encourage your child to recognize the use of fractions in daily life, for example, when filling a glass half full, measuring ingredients for a recipe, or sharing an apple. Here are some activities you can do with your child to help reinforce the concept of fractions:
Fraction Activities
- When you serve your child food, such as a sandwich or an orange, cut it in half (or thirds, or fourths, and so on) and challenge your child to name the fraction for each part. After some is eaten, have your child name the fraction for the parts that are left.
- Provide your child with opportunities to divide food items into equal parts. Have your child tell the fraction name for each part.
- Play a game of “fraction concentration.” On index cards, write fraction symbols, such as , , , …, . Prepare a second set of cards, on which you draw pictures to illustrate each fraction. Shuffle the cards and arrange them face down in a grid.
- To play, take turns turning over two cards.
- If the fraction picture matches the fraction symbol, the player keeps the cards. If not, the player replaces the cards.
- Play continues until all the cards have been matched.
