Today, I will listen to a word problem, record the equation, and add three addends to find an unknown.
Vocabulary
Teacher Resources
Word problem:
Considerations:
There are 5 stars, 8 hearts, and 2 moons on the paper. How many shapes are there in all?
Students need to understand that the unknown can be represented by any letter or symbol.
Use information to write the equation using a letter or symbol for the unknown:
Equations can be written vertically or horizontally.
+
5 8 2 X
13 Unknown
Solve for the unknown:
X = 15
Students need to be aware there are multiple ways to solve each problem.
Steps: 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:
How did drawings help?
MP2: What math symbols did you use today? MP7: Is there another way I can solve this problem?
