Test Booklet

Item Difficulty Analysis 1. Next to each question in your test

booklet, write down the item difficulty. (Higher % means more students answered correctly.)

2. Using item difficulty and the inventory of standards, decide which 5 test questions address content you think your students need more work on.

3. Talk about your list from #2 at your table and construct one list for your table.

Comparing Concepts Is there a another test

question that your students as a whole did better on that is similar to one they did less well on?

How might you explain the difference in performance on similar questions?

Unitizing as a Possible FocusDefinition: The process of constructing

chunks (Lamon, 2005) Example:

Identifying what can be a UnitWhich of these can be considered a “whole?”

If given a whole/part, find a fraction 3rd Grade

If =1

represent 2 ½

4th Grade

If = 1/3, find

5th Grade

If represents 80% of the total stars, how

many stars will you need to make 120%?

If given a whole, represent fractions in multiple ways

3rd GradeSuppose you are decorating your room and want to paint only half of one of your walls. How many different ways can you paint half of the rectangular wall? Be creative!

4th Grade

If this represents a whole, how many different ways can you represent 1/3, 2/6, and 4/12? How are these equivalent fractions based on your pictures?

5th GradeIf represents a whole (1),

how many different ways can you represent , 50%, and ?6

2 6.0

And to conclude… 3rd Grade Best friends Carla and

Eva are in a heated argument. Both say that they were so hungry for dinner, they each ate half of a pizza. Carla argues that she ate more than Eva. Eva said they ate the same amount. Use pictures and words to show how each girl could be right.

4th and 5th Grade Suppose you went

to Costco and bought 24 cans of juice. This would be the same as how many 24-packs? 6-packs? Packs of a dozen? Singles? Half cans? Prove each with a picture.
