Last week in my Kindergarten classroom, my students
practiced using a calculator during a math lesson. First, my mentor teacher
passed out calculators to each of her students and told them to take 5 minutes
to explore and practice using them. After that time was up, she started to
explain how we compute addition on our calculators. The first thing we added
was 2 + 2 = 4. At the beginning, some students were not getting the correct
answer or forgetting steps to get the answer. It seemed clear to me that my
students had not had a lot of experience with calculators. A lot of needed a
lot of support during the lesson. Next, we moved to skip counting by 2s on the
calculator. Then we went onto 5s and finally 10s. The students said that this
strategy could help them practice their skip counting if they become stuck on a
number. They also had a quick discussion and gave situations where we could use
calculators to help them figure out the purpose of calculators and understand
why adults use them. The purpose of the lesson was to teach students strategies
to help them count quickly on calculators. This lesson also helped to give my
Kindergarten students more practice on calculators, since they have not been
exposed to them a lot.
Three questions I have:
1.
How proficient should Kindergarteners be with
calculators?
2.
When do elementary students begin to check their
answers with calculators?
3.
Should we introduce calculators at such a young age?
I could ask my mentor teacher how other students she has
taught were able to use calculators and how much she had to teach them. I could
also ask other Kindergarten teachers if they teach anything about calculators
in their classroom. I could also ask some elementary teachers to see when
students begin to use calculators to make sure they are getting the correct
answers. For my last question, I could ask teachers and read articles that
argue that we should/should not teach students to rely on calculators at such a
young age.
Also try to think of some math tasks that might be good fodder for exploration with calculators - i.e., tasks where you are not using the calculator for the calculator's sake, but rather that the calculator serves as a useful tool that helps to inform the analysis and the problem solving.
