As many of you know we have a new addition to our classroom – the Estimation Machine! Estimation is an important skill for our second graders to develop and it's one they will continue to revisit through the years. The Estimation Machine is a really fun way to bring that skill to life in the classroom.
On Friday morning each student took an estimate. Students were estimating how many warm fuzzies were in the Estimation Machine! A big thanks to Hanna our winner last week for filling up the jar with warm fuzzies from home! Later on in the morning, we went through and counted how many warm fuzzies were actually in the Estimation Machine. We brainstormed possible ways to count all the fuzzies: group them in 2s, 5s, 10s, etc., grouping by 5s was the strategy that won. Ms. LaRose pulled popsicle sticks with students names on them, if your name was called you went to the center of the room and took 5 warm fuzzies We ended doing two rounds of counting. We had 169 warm fuzzies in the container.
When we went through our estimates, Charlie was the winner with an estimate of 155 -- way to go Charlie! Since Charlie was closest he has taken home the Estimation Machine to fill for next week. Next week the student whose estimation is closest to the actual number will take the estimation jar home to refill with a new item. This cycle will continue throughout the school year. Some suggestions for items to put in the Estimation Machine are:
- Animal cookies
- Beads
- Beans
- Bolts
- Bottle caps
- Crayons
- Cotton balls
- Corks
- Drinking straw halves
- Erasers
- Gumballs
- Goldfish
- Macaroni
- Marbles
- Marshmallows
- Nuts
- Paper clips
- Pasta
- Puzzle pieces
- Rubber bands
- Seashells
- Stickers
- Sunflower seeds
- Toothpicks
- Washers
