  1. How do you add mixed numbers with like denominators by replacing them with equivalent fractions? For example: 2 .3 1 + 1 . 3 1

  2. In this lesson, you will learn how to use number lines to add mixed numbers with like denominators by replacing them with equivalent fractions.

  3. Let’s Review A mixed number is made up of a whole number and a fraction. Fraction Whole Number Let’s Review 3 . 4 3 . 4 Numerator: How many parts you have 1 1 Denominator: How many equal parts make up a whole

  4. Let’s Review Mixed numbers can be converted into equivalent fractions. Let’s Review 7 . 3 1 . 3 = 2 3 .3 6.3 0 1 2 3 1 .3 4 .3 5.3 1 .3 1 .3 2.3 7.3 2.3 2.3

  5. A Common Mistake Forgetting that when we compare, add, or subtract fractions, we need to work with the same whole. Let’s Review > + -

  6. Core Lesson + = 2 . 4 1 . 4 3 . 4 2 . 4 1 . 4 2 1 2 1 3 9 .4 1 .4 0 1 2 3 4 2 .4 0 1 2 3 4 6 .4 3 .4 2 .4 1 .4 0 1 2 3 4 15 .4

  7. Core Lesson How could you add mixed numbers with like denominators by changing them into equivalent fractions? 2 .3 1 . 3 1 1 = 3 + 2 .3 1 2 .3 1 .3 5 .3 0 1 2 3 1 . 3 1 4 .3 0 1 2 3 1 .3 0 1 2 3

  8. In this lesson, you learned how to use number lines to add mixed numbers with like denominators by replacing them with equivalent fractions.

  9. Guided Practice Use number lines to add the mixed numbers. Let’s Review + = 1 . 2 1. 2 2 1 0 1 2 3 4 0 1 2 3 4 0 1 2 3 4

  10. Extension Activity Let’s Review Use number lines to add the mixed numbers. 3 . 4 1. 4 1 . 4 3 2 1 + + =

  11. Extension Activity Let’s Review Use number lines to change the mixed numbers into equivalent fractions. 3. 4 4. 6 2 1 = =

  12. Extension Activity Let’s Review Mixed Number Bingo Each student needs a game board and bingo markers. The teacher will hold up a mixed fraction card for students to see. If a student has the picture of that fraction in one of the spaces on the bingo card, he or she may cover that space. The first player who gets five in a row calls out “BINGO!”. The player who calls “bingo” must then read, out loud, the mixed numbers that make bingo. If the student has bingo and can read the numbers, that student wins!

  13. Extension Activity Let’s Review Add the fractions on your paper. Now draw a number line to represent your answers. What do the number lines tell you about the fractions? + = + =

  14. Quick Quiz Let’s Review Use number lines to find the sum. + = 1. 3 1. 3 1 1 A. 0 1 2 3 B. 0 1 2 3 C. 0 1 2 3 D. 0 1 2 3

  15. Quick Quiz Let’s Review Use number lines to find the sum. + = 1. 4 2. 4 A. 1 1 0 1 2 3 B. 0 1 2 3 C. 0 1 2 3 4 D. 0 1 2 3 4
