Grade 3 Worksheet: Exercises 1 to 3
1 Grade 3 Repeated Addition
Exercise 1
Solve using repeated addition:
\(3 \times 7\)
Definition:

Repeated Addition: Multiplication is repeated addition of the same number

\(a \times b = \underbrace{a + a + a + \ldots}_{b \text{ times}}\)

Repeated Addition Method:
  1. Identify the number being added (first factor)
  2. Count how many times it needs to be added (second factor)
  3. Add the same number repeatedly
Expression
\(3 \times 7\)
Repeated Addition
\(3 + 3 + 3 + 3 + 3 + 3 + 3\)
Step 1: Set up the repeated addition

\(3 \times 7\) means adding 3 seven times

Step 2: Perform the addition

\(3 + 3 = 6\), \(6 + 3 = 9\), \(9 + 3 = 12\), \(12 + 3 = 15\), \(15 + 3 = 18\), \(18 + 3 = 21\)

Step 3: Count the total

Adding 3 seven times gives us 21

\(3 \times 7 = 21\)
Final answer:

\(3 \times 7 = 21\)

Applied rules:

• Definition: Multiplication is repeated addition

• Order: \(a \times b = b \times a\) (commutative property)

• Counting: Ensure you add the correct number of times

Tip: Count as you add to avoid mistakes: 1st 3, 2nd 6, 3rd 9, 4th 12, 5th 15, 6th 18, 7th 21
2 Grade 3 Array Model
Exercise 2
Solve using array model:
\(4 \times 5\)
Definition:

Array Model: Organizing objects in rows and columns to visualize multiplication

\(a \times b\) = number of rows × number of columns

Expression
\(4 \times 5\)
Array Model
4 rows, 5 columns
Total
20 objects
Step 1: Draw the array

4 rows with 5 objects each

Step 2: Count by rows

Each row has 5 objects, there are 4 rows: \(5 + 5 + 5 + 5 = 20\)

Step 3: Count by columns

Each column has 4 objects, there are 5 columns: \(4 + 4 + 4 + 4 + 4 = 20\)

\(4 \times 5 = 20\)
Final answer:

\(4 \times 5 = 20\)

Applied rules:

• Visualization: Arrays make multiplication concrete

• Flexibility: Count by rows OR columns, both give same result

• Structure: Helps understand commutative property

Tip: Draw arrays for smaller numbers first to build understanding
Tip: Arrays show why \(4 \times 5 = 5 \times 4\) (same total objects)
3 Grade 3 Skip Counting
Exercise 3
Solve using skip counting:
\(6 \times 4\)
Definition:

Skip Counting: Counting forward by equal intervals (the multiplier)

Count by the first number, the second number tells how many times

Expression
\(6 \times 4\)
Skip Counting
6, 12, 18, 24
Result
24
Step 1: Identify the pattern

Count by 6s, 4 times (because we multiply by 4)

Step 2: Count systematically

1st count: 6, 2nd: 12, 3rd: 18, 4th: 24

Step 3: Identify the final count

After counting by 6s four times, we reach 24

\(6 \times 4 = 24\)
Final answer:

\(6 \times 4 = 24\)

Applied rules:

• Pattern Recognition: Skip counting builds number sense

• Systematic Counting: Keep track of how many counts you've made

• Efficiency: Faster than repeated addition for larger numbers

Tip: Use fingers or tally marks to keep track of counts
Tip: Practice skip counting patterns regularly for fluency

• Distributive Property: \(a \times (b + c) = (a \times b) + (a \times c)\)

Grade 3 Worksheet: Exercises 4 to 5
4 Grade 3 Grouping Strategy
Exercise 4
Solve using grouping:
\(7 \times 3\)
Definition:

Grouping Strategy: Making equal groups of objects to represent multiplication

\(a \times b\) = \(a\) groups of \(b\) objects each

Expression
\(7 \times 3\)
Groups
7 groups of 3
Total
21
Step 1: Understand the grouping

\(7 \times 3\) means 7 groups with 3 objects in each group

Step 2: Create the groups

Group 1: ● ● ●

Group 2: ● ● ●

Group 3: ● ● ●

Group 4: ● ● ●

Group 5: ● ● ●

Group 6: ● ● ●

Group 7: ● ● ●

Step 3: Count all objects

Count all the dots: 3 + 3 + 3 + 3 + 3 + 3 + 3 = 21

\(7 \times 3 = 21\)
Final answer:

\(7 \times 3 = 21\)

Applied rules:

• Equal Groups: Each group must have the same number of objects

• Counting: Count all objects across all groups

• Visualization: Physical representation helps understand multiplication

Tip: Use physical objects like counters or draw circles to represent groups
5 Grade 3 Distributive Property
Exercise 5
Solve using distributive property:
\(8 \times 5\)
Definition:

Distributive Property: Breaking apart one factor to make multiplication easier

\(a \times (b + c) = (a \times b) + (a \times c)\)

Expression
\(8 \times 5\)
Break Apart
\(8 \times (3 + 2)\)
Apply Property
\((8 \times 3) + (8 \times 2)\)
Step 1: Break apart the harder factor

Break 5 into 3 + 2 because 8×3 and 8×2 are easier to compute

Step 2: Apply the distributive property

\(8 \times 5 = 8 \times (3 + 2) = (8 \times 3) + (8 \times 2)\)

Step 3: Calculate each part

\(8 \times 3 = 24\) and \(8 \times 2 = 16\)

Step 4: Add the results

\(24 + 16 = 40\)

\(8 \times 5 = 40\)
Final answer:

\(8 \times 5 = 40\)

Applied rules:

• Decomposition: Break numbers into friendly parts

• Distribution: Multiply each part separately

• Recombination: Add the partial products

Tip: Break larger numbers into tens and ones (e.g., 13 = 10 + 3)
Tip: Use known facts to make harder problems easier
