Arithmetic review: Practicing basic mathematical operations to prepare for final assessment

Arithmetic problem-solving method:
  1. Read the problem carefully
  2. Identify the operation needed
  3. Perform the calculation step by step
  4. Check your answer
  5. Verify the result makes sense
Arithmetic Solutions
A) 45 + 28

45 + 28 = 73

B) 82 - 37

82 - 37 = 45

C) 6 × 7

6 × 7 = 42

D) 48 ÷ 6

48 ÷ 6 = 8

Step 1: Addition (45 + 28)

45 + 28 = 73 (adding tens: 40+20=60, ones: 5+8=13, total: 60+13=73)

Step 2: Subtraction (82 - 37)

82 - 37 = 45 (borrowing: 82 becomes 70+12, then 70-30=40, 12-7=5, total: 40+5=45)

Step 3: Multiplication (6 × 7)

6 × 7 = 42 (6 groups of 7: 7+7+7+7+7+7=42)

Step 4: Division (48 ÷ 6)

48 ÷ 6 = 8 (6 goes into 48 eight times: 6×8=48)

A) 73
B) 45
C) 42
D) 8
Final answer:

A) 45 + 28 = 73, B) 82 - 37 = 45, C) 6 × 7 = 42, D) 48 ÷ 6 = 8. These basic arithmetic operations are fundamental skills for all mathematics and appear frequently on assessments.

Definition:

Geometry review: Studying shapes, their properties, and spatial relationships

Geometry Solutions
A) Rectangle perimeter

P = 2(l + w) = 2(9 + 5) = 2(14) = 28 cm

B) Pentagon sides

Pentagon has 5 sides

C) Square area

A = s² = 6² = 36 cm²

D) 90-degree angle

Right angle

Step 1: Rectangle perimeter

Perimeter = 2 × (length + width) = 2 × (9 + 5) = 2 × 14 = 28 cm

Step 2: Pentagon definition

Pentagon = five-sided polygon (penta = 5)

Step 3: Square area

Area = side × side = 6 × 6 = 36 cm²

Step 4: Angle identification

90 degrees = right angle

A) 28 cm
B) 5 sides
C) 36 cm²
D) Right angle
Final answer:

A) Perimeter = 28 cm, B) Pentagon has 5 sides, C) Area = 36 cm², D) Right angle. Geometry helps us understand shapes and spaces around us.

Applied rules:

• Perimeter: Distance around a shape

• Area: Space inside a shape

• Shape names: Based on number of sides (tri-3, quad-4, pent-5, hex-6, oct-8)

• Angle types: Right angle = 90°, acute < 90°, obtuse > 90°

Data analysis review: Interpreting information presented in tables and charts

Data Analysis Solutions
Student Books Read
Amy 12
Ben 8
Carla 15
David 10
Step 1: Identify highest value

Carla read 15 books (highest)

Step 2: Calculate difference

Carla: 15, Ben: 8, Difference: 15 - 8 = 7 more books

Step 3: Calculate total

12 + 8 + 15 + 10 = 45 books total

A) Carla (15 books)
B) 7 more books
C) 45 total books
Final answer:

A) Carla read the most books (15), B) Carla read 7 more books than Ben (15-8=7), C) Total books read = 45. Data analysis helps us understand and compare information.

Applied rules:

• Comparison: Compare values to find highest/lowest

• Difference: Subtract to find how much more/less

4 Problem-solving review
Exercise 4
Sarah bought 3 packs of pencils. Each pack has 12 pencils. She gave 5 pencils to her friend. How many pencils does Sarah have left?
Show your work and explain your thinking.
Definition:

Problem-solving review: Applying mathematical concepts to real-world situations

Problem-Solving Solution
Step 1: Find total pencils

3 packs × 12 pencils = 36 pencils

Step 2: Subtract given pencils

36 - 5 = 31 pencils

Step 3: Final answer

Sarah has 31 pencils left

Step 1: Calculate total pencils

Sarah has 3 packs with 12 pencils each: 3 × 12 = 36 pencils

Step 2: Subtract pencils given away

She gave 5 pencils to her friend: 36 - 5 = 31 pencils

Step 3: State the answer

Sarah has 31 pencils remaining

Sarah has 31 pencils left
Final answer:

Sarah has 31 pencils left. First, I multiplied 3 packs by 12 pencils per pack to get 36 total pencils. Then I subtracted the 5 pencils she gave away to find that she has 31 pencils remaining. Problem-solving requires understanding what operations to use.

Applied rules:

• Multiplication: Use when finding totals for equal groups

• Subtraction: Use when finding what remains after giving away

• Problem analysis: Identify what is happening in the situation

• Operation selection: Choose correct mathematical operation

5 Mixed concepts review
Exercise 5
The garden has 4 rows of flowers. Each row has 8 flowers. If each flower needs 2 cups of water, how many cups of water are needed in total?
Also, what is the perimeter of the rectangular garden if each row is 10 meters long and the width is 5 meters?
Definition:

Mixed concepts review: Combining multiple mathematical topics in complex problems

Mixed Concepts Solution
Water calculation

4 rows × 8 flowers × 2 cups = 64 cups

Perimeter calculation

P = 2(l + w) = 2(10 + 5) = 2(15) = 30 meters

Step 1: Find total flowers

4 rows × 8 flowers per row = 32 flowers

Step 2: Calculate total water needed

32 flowers × 2 cups per flower = 64 cups of water

Step 3: Calculate perimeter

Length = 10 meters, Width = 5 meters

Perimeter = 2(length + width) = 2(10 + 5) = 2(15) = 30 meters

Water needed: 64 cups
Garden perimeter: 30 meters
Final answer:

For watering: 64 cups of water are needed. For the perimeter: 30 meters. This problem combines multiplication (for total flowers and water) with the perimeter formula for rectangles. Mixed concept problems test your ability to apply multiple skills.

Applied rules:

• Multiplication chains: Multiply all relevant quantities

• Formula application: Use correct geometric formulas

• Multiple steps: Break complex problems into smaller parts

• Verification: Check that each part of the answer makes sense
