Water Collector
Tori needed to collect exactly 6 gallons of water from a local stream to test its cleanliness. Unfortunately, she had only a 4-gallon jug and a 7-gallon bucket!
“That’s OK,” she said. “I know how to get just the right amount of water using only these two tools!”
How did Tori collect exactly 6 gallons of water?
Patchy Equation
At Thrifty Treasures, old clothes are repaired and sold to math-loving customers. Help choose which patches should be sewn on this shirt and in what order so that it shows a true equation.
Key:
Rectangles Galore!
How many rectangles can you find in this shape?
Don’t forget that some large rectangles may have smaller rectangles inside!
Tori's Trees
When Tori volunteered to plant trees in her neighborhood, she decided to plant them in a pattern.
Draw how she planted the next plot.
ANSWERS: Water Collector: Tori filled the 7-gallon bucket then poured it into the 4-gallon jug, leaving 3 gallons behind. She then dumped out the 4-gallon jug and poured the 3 gallons into it. Next, she refilled the 7-gallon jug, poured 1 gallon into the 4-gallon jug, and was left with 6 gallons; Rectangles Galore!: There are as many as 90 rectangles, all answers between 1 and 90 are valid; Tori’s Trees: The pattern is multiply by 2, subtract 3, so the next plot should have 11 trees; Patchy Equation: 5 x 8 – 2 = 38 or 8 x 5 – 2 = 38.
