For some reason, most of the Grade Ones that I've ever taught, do not want to estimate and they don't understand why they should practice the skill. To them, the right answer is the right answer and "why should I guess first ... why don't I just count it instead?"Estimating is an important skill. I want students to be able to determine the reasonableness of their answer. Without estimation skills, students aren’t able to determine if the answer to a math problem is reasonable. When a mistake is made, students need to be able to see that it just wouldn't be possible for 10+1 to be 20.
We will be doing an Estimation Jar activity during our math periods. I will place random items in a jar and encourage the students to think about the size of the items and the size of the container. Reasonable estimates will be celebrated. See how we did this week ...
