Reflection: Perseverance Large Number Lines - Section 3: Try It Yourself


During this section of the lesson when the students were working between 1/2 and 1, several of them had difficulty determining the next fraction after one half. The strategy they had used of finding fractions smaller than one half needed to be switched.  This required the students to reorder their fraction strips and created a struggle for the students to switch their process and strategy for determining the next fraction. 

One of the students shared his strategy of just laying the fractions on his desk, rather than holding them folded up in his hand find the next fraction.  This strategy seemed to help many of the students, as they listened to his reasoning and demonstration.  The other students were able to follow his example and complete the task.  This student helped other students after he finished his own number line.

Large Number Lines

Unit 4: Fractions
Lesson 9 of 18

Objective: SWBAT order fractions on a number line, create models of unit fractions, and identify equivalent fractions.

Big Idea: Using large number lines provides an opportunity to use a large strip of paper to represent the whole amount and conceptualize how fractional amounts changed based on the size of the whole amount.

Big Idea: Naming unit fractions is a start, but helping students visualize how they can be grouped together to make a larger part of a whole is the focus of today's lesson.
