Dear LOR user,

Thank you for being a big part of this community. To better support the initiatives around open educational resources in the state of Michigan, all resources on the Michigan Virtual Learning Object Repository (LOR) are being moved to #GoOpen Michigan (link is external) on September 30th, 2018. During the transition, our LOR will be moved to an archived state, not allowing new user registration or new content to be added. An email with more details was sent to registered users of the LOR in September. To make use of the great resources on the platform, we encourage you to create an account and add your own new resources to the #GoOpen Michigan platform (link is external).

4th Grade Measurement Unit

Description: 

This unit is basically chapter 5 in our Math Expressions curriculum.  If your district uses Math Expressions, then this unit will make a lot of sense to you.  If you don't have Math Expressions, this unit can still help guide you through teaching your kids meausurement using customary and metric systems.

Learning Targets: 
I can know the relative size of different units in length, weight, capacity, and time.
I can express how many smaller units are in a larger unit.
I can solve word problems by using multiplication, division, addition, and subtraction when the story problem deals with measurement topics.
I can use area and perimeter to solve problems involving real world problems regarding rectangles.

How are the standards/objectives assessed?

I use a couple of quizzes to get formative assessment data that I use to reteach my kids through this unit.  I also use a final chapter test to get their final grades.

Student prerequisite skills and knowledge

You need to know how to add and multiply in order to find measurement conversions and area / perimeter.  The kids should be able to multiply at least 2 digit by 2 digit numbers if needed to find the area of a larger rectangle.

How is the concept or procedure explained or demonstrated?

Math Expressions uses a series of lessons to guide students through this chapter.  I took this chapter and put it into a day by day format that shows how I go through it.  The measurement lessons build on each other day to day.

What concepts or procedures are being explained or demonstrated in this lesson object?

The first chunk of this unit teaches about metric measurement units and how to convert them.

The second chunk of this unit teaches about customary measurement units and how to convert them.

The last chunk of this unit teaches about area and perimeter.  

What was your experience, both successes and challenges, using this lesson object with your students?

I provide my students with a cheat sheet for both the metric and customary measurements.  Heavily stress that when they are converting a larger unit to a smaller unit (feet to inches) they always multiply.  If you stress this over and over, they should be ok.  For area and perimeter, I really stress the formulas and what area and perimeter really are before just diving into problems.  Teaching kids the prefixes in the metric lessons can help them as well and I also stress that the metric system always increases or decreases by a power of 10.  For example, CENTImeters are 10 times LARGER than MILLImeters.
