Conservation Challenge Sanctuary expansion
A wildlife sanctuary expansion project has the following details:
- 24 new enclosures will be built
- Each enclosure needs 16 fence posts
- Fence posts come in bundles of 18
- Each bundle costs 145 BWP
- The project also needs water systems: 8 tanks per enclosure
- Water tanks cost 234 BWP each
- Total budget: 95,000 BWP
Tasks:
• How many fence posts needed total?
• How many bundles needed? (Interpret remainder!)
• What's the fence post cost?
• What's the water tank cost?
• What's the total cost?
• Is the project within budget? By how much over/under?
Extension: If 5% of the remaining budget goes to maintenance, how much is that?

Share Equally
Explicit Instruction:
Let's share equally.
Problem 1: Simple Equal Sharing
A conservation team has 12 energy bars to share equally among 4 rangers.
12 ÷ 4 = 3
Each ranger gets 3 bars
All 12 bars used, nothing left over
Explicit Instruction:
Let's share equally.
Problem 2: Sharing the RemainderA team has 14 energy bars to share equally among 4 rangers.
14 ÷ 4 = 3 R2
Traditional answer: 3 each, 2 left over
3 whole bars + 2 quarters = 3½ bars
Explicit Instruction:
Let's use division
The whole = 20 beds
Problem 3: Visualizing Parts of WholesA garden has 20 plant beds. One-quarter (¼) are growing vegetables.
To find ¼, we divide by 4
20 ÷ 4 = 5
So ¼ of 20 = 5 beds

Mystery Number 2:
• I'm a 2-digit number • When rounded to nearest 10, I become 90 • When you divide me by 7, the remainder is 1 • I'm greater than 85 • What number am I?
Mystery Number 3:
I'm a 4-digit number • Rounded to nearest 1,000, I'm 5,000 • All my digits are different • My hundreds digit is 3 • I'm greater than 5,200 What number am I?
Mystery Number 1:
• I'm between 100 and 200 • When you divide me by 5, there's no remainder • I have a 5 in the tens place • I'm less than 160 • What number am I?
