Reflection: Joy All Hands In for Improper Fractions - Section 3: Concept Development


This lesson was so fun to deliver and observe my students making connections.  The use of unifix cubes as manipulatives is something new I tried this year and I definitely will use it again in future lessons.   Students were able to group cubes together to visually see the wholes and parts in order to make sense of converting mixed number to an improper fraction.  I even had several students tell their homeroom teacher about using the cubes to model improper fractions which sparked that teacher's interest. She came into my room later in the day and wanted me to show her.  She too, said she'd never used cubes before to help teach fractions and thought the method was very helpful.  

If I could change one thing about this lesson, I would incorporate more sharing out during the lesson of students strategies as they discovered shortcuts for converting.  We ran out of time towards the end and it felt too rushed. 

You can listen to my reflection video below for more thoughts about using cubes to teach fractions.
