Quiz 2 : Multiplication Word Multi-Step Problems: 1x2,1x3,1x4 digit and estimation - Section 1: Warm Up: Quick Review to Get Ready

**A CCSS Breakthrough in class!** *One of my hopes as I teach CCSS is that students start to show thinking and reasoning about their math. I know it comes very slowly. Sometimes, especially with word problems, I never think it will happen. Students have been so engrained to solve problems without thinking that this has been really tough. During the review an amazing thing happened! The equation for the first word problem produced a double digit by double digit problem. I mentioned that they hadn't been instructed to solve a double digit by double digit problem yet. I suggested that they multiply each set of peanut butter cases against the amount of jars instead to avoid the double digit by double digit equation. *

*One of my students raised her hand and said..." But yes we can solve it, Mrs. Kanthack, we just need to pull apart one of the factors and multiply it using expanded form."*

*I about fell over.*

*Thinking! How refreshing! CCSS are taking hold? I hope so! I jumped up and down, did a happy dance, and really praised her thinking.*

*CCSS Breakthrough!*

# Quiz 2 : Multiplication Word Multi-Step Problems: 1x2,1x3,1x4 digit and estimation

Lesson 9 of 19

## Objective: SWBAT show what they know about solving multi step word problems

As I prepared this quiz for my students, I was thinking about the past word problem work they had done and the conversations we had about equations. I felt anxious that they weren't really understanding that equations should drive their solutions to word problems, so I developed a quick review for them and re-taught solving word problems by emphasizing the standard and developing the 4 steps they needed to achieve it. The Warm UP Review for Word Problems for Quiz 2 helped students refresh their minds and give them a chance to look over their notes as we worked through the review. We developed equations together on the whiteboard alongside the SB file and I answered questions about variables, underlining nouns for labels and the words that told them when it was necessary to estimate instead of finding the exact answer.

#### The Quiz

*40 min*

I handed out Quiz 2 Multiplication Multi-Step Word Problems Using 1 Digit Up to 4 digits and they set to work. We read directions aloud. The assessment includes a point for showing a method of organizing understanding of the word problem because they are not fluent enough yet in organizing it in their heads. That written evidence of their thinking is so important to me to see, so I can fully assess if they have mastered the standards. Even my above grade level students need this, especially with multi-step word problems. I also included points for equations with variables. And lastly, I wanted to see the transfer of understanding from the variable to the accuracy of the solution and the label.

There are two estimation problems and two exact answer problems. I expected them to read the language and interpret the problem correctly based on identification of the proper vocabulary used for estimation.
