  • EXPLAIN to the students that you will be relearning how to add and subtract fractions with like denominators in word problems.

Adding Fractions with Like Denominators Question

  • PLAY the Khan Academy “Piano” lesson. Stop the lesson after each arrow is drawn on the screen and DISCUSS why these arrows are important and why visuals are important. PLAY lesson. STOP after the equation ¾ - ¼ = is given. EXPLAIN why he chose to you subtraction in the equation. After the video ends, RE-EXPLAIN simplifying to the students and ASK if anyone has any questions.
  • WRITE or PROJECT on the board a similar question: Sally is supposed to cut a loaf of bread into 8/12. She has already cut the bread into 4/12. What fraction does she still need to cut? WORK together as a class (asking them to give the step by step) to answer the question.

Subtracting Fractions with Unlike Denominators Question

  • PLAY the Khan Academy “Lizard” lesson. STOP the lesson after he counts the extra 8 marks in the inch. DISCUSS and EXPLAIN why he has done this. PLAY lesson. STOP after he quickly say 8 goes into 17, 2 times with a remainder of 1. REMIND your students how this works. (18/4 = long division 18 divided by 4 = 4 goes into 18, 4 times with a remainder of 2. Do this with two more problems. 13/3 and 29/6).  PLAY lesson. STOP after he counts off the additional 10. DISCUSS and EXPLAIN why he added the 10 instead of starting over. PLAY lesson. STOP before he gives the mixed number answer. STUDENTS WORK have the students try to get the correct answer. Have the students flip their paper over and put their pencils down once they work out the problem. PLAY lesson and show the answer. ASK the students to give a thumbs up or down if they got the answer correct. WALK around to see who missed it and pull them aside after the lesson.
  • WRITE or PROJECT on the board a similar question:
