Presentation Transcript

  1. Study these pictures. Lesson 2 – Adding Fraction Pictures On your scratch paper write a fraction for the first picture. Write a plus sign and write a fraction for the second picture. 3 + 3 4 4 Check your work. + 3 3 . 4 4

  2. Now add the fractions for both pictures and write an equal sign. Write the total number of fourths you get when you add both pictures together. Yes! If you add 3 and 3 you get 6 . 4 4 4 = + Here is a picture of what you get if you add 3 and 3 . 4 4 You get 6 . 4

  3. Here’s a new problem. + On your scratch paper write a fraction for the first picture. Write a plus sign and write a fraction for the second picture. Check your work. + You get 1 5 . 3 3 +

  4. Now add the fractions for both pictures and write an equal sign. Write the total number of thirds you get when you add both pictures together. + Yes! If you add 1 and 5 you get 6 . 3 3 3 = Here’s a picture of what you get if you add 1 and 5 . 3 3 You get 6 . 3

  5. Let’s try another problem. + On your scratch paper write a fraction for the first picture. Write a plus sign and write a fraction for the second picture. Check your work. + The fractions are 3 and 4 . 2 2

  6. Now add the fractions for both pictures and write an equal sign. Write the total number of halves you get when you add both pictures together. Yes! If you add 3 and 4 you get 7 . 2 2 2 + = Here’s a picture of what you get if you add 3 and 4 . 2 2 You get 7 . 2

  7. One Last Problem. Study these pictures. On your scratch paper write a fraction for the first picture. Write a plus sign and write a fraction for the second picture. Check your work. + The fractions are 2 and 3 . 6 6

  8. Now add the fractions for both pictures and write an equal sign. Write the total number of sixths you get when you add both pictures together. Yes! If you add 2 and 3 you get 5 . 6 6 6 + = Here’s a picture of what you get if you add 2 and 3 . 6 6 You get 5 . 6

  9. + + + + On your scratch paper write the fraction for each picture. Write the fraction for the total. (Remember to use the + and = signs.) 1. 2. 3. 4. = = + + + = + =

  10. + + + + Check your work. 1. 2. 2 4 3 4 1 4 2 5 2 5 4 5 + = = + 3. 4. 2 2 2 2 3 2 5 2 1 2 3 2 4 2 + + = =
