Slide 1: Estimation with Division

• Estimation is a helpful tool in math to get a quick answer without doing precise calculations.
• When estimating 3,280 ÷ 4:
  • Round 3,280 to the nearest hundred: 3,300.
  • Divide: 3,300 ÷ 4 = 825.
• So, the estimate for 3,280 ÷ 4 is approximately 825.

Slide 2: Solving a Division Problem

• Let's solve the division problem 1,815 ÷ 5.
• First, think of how many times 5 goes into 1,815:
  • How many 5's fit into 8? (1 time: 5)
  • How many 5's fit into 31? (6 times: 30)
  • How many 5's fit into 15? (3 times: 15)
• The answer is: 363.

Slide 3: Dividing a Larger Number

• Now we'll divide 6,636 ÷ 3.
• Break it down step by step:
  • Start with the first digit: how many times does 3 go into 6? (2 times)
  • Then consider the next digits: 63 ÷ 3 = 21, bringing down the 6 makes 2,212 overall.
• The answer is: 2,212.

Slide 4: Real-World Problem - Packing Cookies

• A baker makes 574 cookies and wants to pack them into boxes of 7.
• To find out how many boxes are needed:
  • Divide 574 cookies by 7 boxes: 574 ÷ 7.
  • Estimate first: 560 ÷ 7 = 80 (around this many).
• Perform the calculation to find the exact number of boxes required.

Slide 5: Summary and Importance of Division

• Division helps us share items equally and solve problems in daily life.
• We practiced:
  • Estimation
  • Solving exact division problems
  • Applying division in real-world scenarios
• Remember, it's important to check your work and make sure your answers make sense!
