Drawings:
Considerations:
+
=4
If manipulatives are not easily available, consider using beans, squares of colored paper, etc., as objects to be counted. Drawings do not need to be detailed. They only need to represent the mathematical thinking. Consider using simple shapes.
Addition equation:
3+1=4
Emphasize words and phrases such as in all, altogether, and total as words that mean addition. Math vocabulary is provided in the Student Journal.
Steps: 1. Listen carefully to get information from the word problem. 2. Use counters or drawings to solve the problem. 3. Record the equation.
Application of MPs: MP1:
How did drawings help you in today’s lesson?
MP2: What math symbols did you use today? MP6: How do you know your answer is reasonable?
/ *MP1: Make sense of the problem and persevere in solving it! *MP8: Find a strategy to help solve the problem. Directions: Use objects and drawings to model solving the following word problems.
1. There are 4 birds sitting in a tree. Three more birds come. How many birds are there in all?
State the objective: Today, I will solve addition story problems using objects and drawings.
Explain that the first step is to carefully listen to the word problem to get the information needed to find the sum.
Emphasize that the words “in all” mean to add.
Model how to count out 4 objects for the birds sitting on the tree and then 3 more for the birds that come. Then, put all objects together and count how many objects there are in all.
Record the addition equation and sum.
4+3=7 2. Noe has 8 baseballs. Vy has 2 baseballs. How many baseballs do they have altogether?
Restate the objective: Today I will solve addition story problems using objects and drawings.
Explain that the first step is to carefully listen to the word problem to get the information needed to find the sum.
Emphasize that the word “altogether” means to add.
Model how to draw 8 circles for Noe’s 8 baseballs and then 2 more for Vy’s baseballs. Then, count all drawings to find out how many there are altogether.
Directions: Students use objects and drawings to solve the following word problems.
1. There are 6 cats and 3 dogs. How many animals are there in all?
+
=
2. Pedro picked 9 apples. Ali picked 4 more. How many apples did they pick altogether?
+ +
= =
*MP3: Do you agree/disagree with what
said?
*MP6: How do you know your answers are correct/reasonable?
Recap today’s lesson with one or more of the following MP questions: MP1: How did drawings help you in today’s lesson? MP2: What math symbols did you use today? MP6: How did you know your answer is reasonable?
