On the first warm days of spring, do math outside!
The Water Jug Riddle*
Required:
1, 3, 5 and 8 quart jugs and unlimited access to water, such as a spigot or hose.
Instructions:
Easier: You have 3 jugs that hold 1, 3, and 5 quarts of water.
Task 1: Give me a container holding exactly 2 quarts of water.
Task 2: Give me a container holding exactly 4 quarts of water.
More Difficult: You have 3 jugs that hold 3, 5, and 8 quarts of water.
Task: Give me a container holding exactly 4 quarts of water.
Can you figure out how to solve each one?
Time Lapse*
Required: watch
Notes:
Good activity to prepare students for a presentation since everyone winds up sitting quietly.
Some reward for the 'winner' might be first in line for snacks or first up for next game.
Instructions:
Everyone stands and closes their eyes.
On 'GO' signal from the leader with a watch, everyone tries to estimate when a minute (60 seconds) has elapsed while keeping their eyes closed. When you think it has been a minute, you sit down.
The student that sits closest to a minute wins.
An alternative is to have everyone do an activity for exactly one minute- jog in place, do jumping jacks, hop from foot to foot, turn in circles...
*Both ideas come from the Boy Scouts
Place Value Hopscotch
Create a place value hopscotch board with sidewalk chalk, one for each group of 3 or 4. (You can include higher values or decimals as well). One player hops and the other watches and figures out the number.
3 times on the 1,000
2 times on the 10, 000
After students take turns hopping a couple times, have them compare the numerals they made. Which number is the largest? Who created the smallest number? Can they point out the odd and even numbers they created?
