Accepted Answer

### Problem 1
# Explanation:
## Step1: Identify the operation
Tamara has 3 practices per week, for 7 weeks. So we use multiplication: $ 3 \times 7 $.
## Step2: Calculate the product
$ 3 \times 7 = 21 $.
# Answer: 21

### Problem 2
# Explanation:
## Step1: Identify the operation
David has 24 items, putting 3 in each bag. We use division: $ 24 \div 3 $.
## Step2: Calculate the quotient
$ 24 \div 3 = 8 $.
# Answer: 8

### Problem 3
# Explanation:
## Step1: Calculate $ 7 \times 4 $
$ 7 \times 4 = 28 $.
## Step2: Calculate $ 1 \times 4 $
$ 1 \times 4 = 4 $.
## Step3: Add the results
$ 28 + 4 = 32 $.
# Answer: 28, 4, and 32 (when added)

### Problem 4
# Explanation:
## Step1: Calculate $ 8 \times 4 $
$ 8 \times 4 = 32 $.
## Step2: Compare with Problem 3
The result from Problem 3 (when adding 28 and 4) is also 32, so yes, the answers are the same.
# Answer: $ 8 \times 4 = 32 $; Yes, the answers are the same.

### Problem 5
# Explanation:
## Step1: Find area of first small rectangle
The first small rectangle has dimensions 3 (width) and 5 (height). Area: $ 3 \times 5 = 15 $.
## Step2: Find area of second small rectangle
The second small rectangle has dimensions 3 (width) and 2 (height). Area: $ 3 \times 2 = 6 $.
## Step3: Add the areas
$ 15 + 6 = 21 $? Wait, no, wait the total height is 7 (5 + 2). Wait, maybe I misread. Wait the large rectangle: first part is 3 columns, 5 rows: $ 3 \times 5 = 15 $. Second part: 3 columns, 2 rows: $ 3 \times 2 = 6 $. Total area: $ 15 + 6 = 21 $? Wait no, wait 3*(5+2)=3*7=21. Wait, but let's check again. Wait the figure: 3 columns, 5 rows (height 5) and 3 columns, 2 rows (height 2). So area of first: 3*5=15, second: 3*2=6. Sum: 15+6=21.
# Answer: 21

### Problem 6
# Explanation:
## Step1: Identify dimensions of large rectangle
The large rectangle has width 3 and height 7 (5 + 2).
## Step2: Calculate area
Area = width × height = $ 3 \times 7 = 21 $.
# Answer: 21

### Problem 7
(Note: Since the strategy card is not shown, a general example. For a multiplication problem, two strategies could be: 1. Repeated addition (e.g., for $ 5 \times 3 $, do $ 3 + 3 + 3 + 3 + 3 $). 2. Using arrays (drawing a grid with 5 rows and 3 columns and counting the squares).)
# Brief Explanations:
For a multiplication - related problem (as seen in previous problems), one strategy could be repeated addition (e.g., to solve $ n\times m $, add $ m $ a total of $ n $ times). Another strategy could be using an array model, where you draw a rectangle with $ n $ rows and $ m $ columns and count the number of unit squares to find the product.
# Answer: (Example) 1. Repeated Addition (e.g., for $ 4\times5 $, calculate $ 5 + 5 + 5 + 5 $). 2. Array Model (draw a 4 - row, 5 - column grid and count the squares).
