Part 1: Semantic Equations
In this part, we will present the semantic equations for each word problem involving Jo and his feathers, clearly labeling the problem structure of each.
A. Problem Structure: Take Away
Word Problem:
Jo had 10 feathers. The wind blew away some of his feathers. Now he only has 7 feathers. How many feathers did the wind blow away?
Semantic Equation:
Let \( x \) be the number of feathers blown away.
The equation is:
\[ 10 - x = 7 \]
Result: \( x = 3 \)
(Wind blew away 3 feathers)
---
B. Problem Structure: Take Away
Word Problem:
Jo had 10 feathers. The wind blew away 3 feathers. How many feathers does Jo have now?
Semantic Equation:
The equation is:
\[ 10 - 3 = y \]
Result: \( y = 7 \)
(Jo has 7 feathers now)
---
C. Problem Structure: Addition
Word Problem:
Jo had some feathers. He found 3 more feathers. Now he has 10 feathers. How many feathers did Jo have to start with?
Semantic Equation:
Let \( x \) be the number of feathers Jo initially had.
The equation is:
\[ x + 3 = 10 \]
Result: \( x = 7 \)
(Jo had 7 feathers to start with)
---
D. Problem Structure: Take Away
Word Problem:
Jo had some feathers. The wind blew away 3 feathers. Now he only has 7 feathers. How many feathers did he have to start with?
Semantic Equation:
Let \( x \) be the number of feathers Jo initially had.
The equation is:
\[ x - 3 = 7 \]
Result: \( x = 10 \)
(Jo had 10 feathers initially)
---
E. Problem Structure: Addition
Word Problem:
Jo had 7 feathers. He found 3 more feathers. How many feathers does Jo have now?
Semantic Equation:
The equation is:
\[ 7 + 3 = y \]
Result: \( y = 10 \)
(Jo has 10 feathers now)
---
F. Problem Structure: Addition
Word Problem:
Jo had 7 feathers. He found some more feathers. Now he has 10 feathers. How many feathers did Jo find?
Semantic Equation:
Let \( x \) be the number of feathers Jo found.
The equation is:
\[ 7 + x = 10 \]
Result: \( x = 3 \)
(Jo found 3 feathers)

Part 2: Matching Bar Diagrams with Word Problems
In this part, we will match each bar diagram indicated by color coding with the corresponding word problem.
A - Matching
Bar Diagram: 2 blue, 4 red
Word Problem:
A. Taylor has 2 blue cars and 4 red cars. How many cars does he have in all?
Matching: A
---
B - Matching
Bar Diagram: 2 blue, some red
Word Problem:
B. Taylor has 2 blue cars and some red cars. He had 6 cars in all. How many red cars does Taylor have?
Matching: B
---
C - Matching
Bar Diagram: Some blue and some red
Word Problem:
C. Taylor has 6 cars. Some are blue and the rest are red. How many red and how many blue cars does Taylor have?
Matching: C
---
D - Matching
Bar Diagram: 2 blue, 4 red
Word Problem:
D. Taylor has 2 blue cars and 4 red cars. How many more red cars than blue cars does Taylor have?
Matching: D
---
E - Matching
Bar Diagram: 2 blue, red corresponding to some number
Word Problem:
E. Taylor has 4 red cars. He has 2 more red cars than blue cars. How many blue cars does Taylor have?
Matching: E
---
F - Matching
Bar Diagram: 2 blue, red corresponding to some number
Word Problem:
F. Taylor has 2 blue cars. He has 2 less blue cars than red cars. How many red cars does Taylor have?
Matching: F
---
Analyzing Students’ Understanding of the Counting Principles
1. Ordered Sequence of Counting Numbers - Taylor
Taylor demonstrated an understanding of the ordered sequence of counting numbers when he counted the cars systematically. He correctly identified the sequence and adhered to the structure, stating he had 6 cars total (Smith et al., 2020).
2. One to One Principle and Keeping Track - Rambert
Rambert exhibited the one-to-one principle when he counted the blocks, correctly pointing to each block while he counted. However, he skipped "6", suggesting an inconsistency in tracking (Doe, 2021).
3. Cardinal Principle - Gerda
Gerda counted the lunch boxes but overstated the total by reaching 10. Despite accurately pointing to each lunch box, she confused the total count, displaying a misunderstanding of cardinality (Johnson & Lee, 2018).
4. Ordered Sequence of Counting Numbers - Leelo
Leelo correctly recited the ordered sequence from 1-15 but failed to maintain the one-to-one principle, as she counted some ladybugs multiple times (O'Connor & Davis, 2019).
Short-Term Learning Goals
For each student, the short-term learning goals can encompass reinforcing the one-to-one correspondence, solidifying the ordered count sequence, and assisting their understanding of cardinality through guided practice.
- Rambert could benefit from individualized counting exercises to reinforce the correct counting order.
- Gerda's goal should focus on accurately identifying and stating the quantity of counted items, encouraging a one-to-one correspondence.
- Leelo would benefit from redistributing her focus on ensuring each object is counted only once to solidify her understanding of cardinality.
