Reflection: Positive Reinforcement Solving Multi-Step Word Problems Given a Part to Part Ratio - Section 4: Whole Group Discussion

 

We discussed question 1 during the whole group discussion. Through the discussion, the most common mistake made was that the students were not able to identify and calculate the whole.  The students had a hard time with 1 1/2 as a part.  Once I modeled how to illustrate the parts they were able to add the parts together with ease.  Several students put a block up when it comes to mixed numbers, improper fractions, and fractions.  When students were faced to add 1 1/2 to 5 it was difficult, the moment they illustrated the 1 1/2 and the 5 and counted what they illustrated it was as if the Red Sea parted. Students using MP 4 to help them solve this problem was key.  Students also struggled with understanding they needed the whole in order to solve the problem.  I went back to our part to whole examples and compared how we solved those problems with what we did in this lesson.  That coherence piece also aided in understanding.
