Today, I will listen to a word problem, record the equation, and add three addends to find an unknown.
Vocabulary
Teacher Resources Considerations:
+
3 4 6 Y
Students need to understand that the unknown can be represented by any letter or symbol.
7 Unknown
Students need to be aware there are multiple ways to solve each problem. Equations can be written vertically or horizontally.
Y = 13
Steps:
5 + 2 + 5= 7
= 12
(unknown)
1. Listen carefully to the word problem and write down the information needed to solve using a letter or symbol to represent the unknown. 2. Add two of the three addends together. 3. Add the sum of those addends to the third addend. 4. Solve for the unknown.
Application of MPs: MP1:
What did you do first? Why?
MP4: How can you relate this to something in real life? MP8: What strategies did you use to help solve the problems?
