Lesson Outline 0011 0010 1010 1101 0001 0100 1011 Today we are going to: Review the Four Step Plan to Solve Math Problems Identify the four math operations Identify clue words that tell us which math operation we need to use. 1 2 4

Review 0011 0010 1010 1101 0001 0100 1011 Yesterday we talked about the four step plan to solving math problems. To help us review the steps to solve math problems, you are going to do a matching game in your small groups. Look at your work system and get out your blue folder. You should work in your small groups to put the steps in order. 1 2 4

What is a math operation? 0011 0010 1010 1101 0001 0100 1011 Addition Subtraction Multiplication Division 1 2 4

When you are asked to identify a math operation, you are being asked if you should add, subtract, multiply, or divide! 0011 0010 1010 1101 0001 0100 1011 1 2 4

Why do we need to learn math clue words? 0011 0010 1010 1101 0001 0100 1011 Word problems do not specifically tell us to add, subtract, multiply, or divide. 1 2 4 We need to know the clue words so we can determine if we should add, subtract, multiply, or divide.

I should add when I see 0011 0010 1010 1101 0001 0100 1011 Sum Total Increased by Together Altogether Both In all 1 2 4

I should subtract when I see 0011 0010 1010 1101 0001 0100 1011 Decreased by Minus Difference How many more How much more Take away 1 2 4

I should multiply when I see 0011 0010 1010 1101 0001 0100 1011 Of Times Product of 1 2 4

I should divide when I see 0011 0010 1010 1101 0001 0100 1011 Per Quotient of 1 2 4

Let’s practice 0011 0010 1010 1101 0001 0100 1011 Using the multiple choice cards, you should work with your group to identify the math operation that matches the clue word. 1 2 4

Let’s Practice 0011 0010 1010 1101 0001 0100 1011 To see how many of the clue words you remember, you are going to complete a fill-inthe-blank activity. The fill-in-the-blank activity is in your yellow folder. 1 2 4 The completed activity will be used as a resource for you as we solve math problems throughout the year.

Match Time! 0011 0010 1010 1101 0001 0100 1011 You are going to work with your small group to complete a matching activity. In the envelope you will find two sets of cards. Some of the cards will have math operations written on them. Other cards will have sentences from word problems that contain some of the clue words. You are going to match the clue words to the math operation. 1 2 4
