## Reflection: Checks for Understanding Determining Equivalency between Grams & Kilograms - Section 4: Closing

Although the majority of students demonstrated proficiency today on the exit slip, a couple students struggled with grasping these new concepts. Here's an example of a Novice.jpg level on the exit slip.

1. How many grams equals 1 1/2 kg?

This student answered 500. He's almost there! He understands that 1/2 kilogram = 500 grams, but is having trouble with adding in the whole kilogram.

2. How many grams is 2.5 kg?

This student answered 300. This shows that this student needs extra support with fraction/decimal relationships. He also needs to be provided with more models, such as a long number line where we take jumps of a 1/2 kg up to 5 kg. Then we could go back and apply decimal numbers to the same number line.
