| Word Problems using a Bar Model (aka Tape Diagram) and the RDWW strategy we use in class: R ead the word problem & extract (underline) the information needed to solve the problem Draw picture to represent the problem Write a number sentence horizontally to represent your drawing Write an explanation of your answer to check for reasonableness |
