Mixed and Improper Fractions
Kal-El used the fraction cut-outs box that I tucked under the fractions cabinet for the first time this week. The end goal was to get to the addition of fractions which create sums greater than a whole. However, first I gave him a presentation on the nomenclature for proper, apparent, improper, and mixed fractions. I saw this presentation done in a video on Montessori Live. If it is any of my albums I've missed seeing it (Found it. It's in the second MRD fractions manual).
This presentation was a great stepping stone to the addition lesson because it instilled the idea that while sometimes we have reason for using or stating an improper fraction most of the time it needs to be transformed into a mixed fraction. The fraction pizza game that we've been playing was a great stepping stone as well. We were able to think back to "creating as many pieces as possible" to find our whole number and then recorded what was left over as a proper fraction.
Afterward Kal-El was ready to jump into his next drawer of command cards in his fraction cabinet. He has been filling in a page full of these in his fraction notebook every day this week. Yesterday he was extra appreciative of the fraction cut-out box versus the wooden fraction insets in frames because he could take his work outside! I hope to wrap up our week tomorrow with a "school days" post showing you all of the work we did outside. The neighbor is having a fence installed and we have been doing all of our schoolwork outdoors so we can watch.
