What Part of the Square is Shaded?
Estimation Exploration
About how much of the square is shaded?
Why is estimating the shaded region more difficult without the gridlines of a hundredths grid?
Represent Thousandths on a Grid
Today we are going to represent decimal numbers with diagrams. Think about yesterday's lesson. What does the decimal 0.001 mean?
Video: Fractions and Decimals on a Grid
Let's review what we learned about decimals and fractions on a grid. The Edio lesson contains a short video to help us review.
Decimals on a Diagram
On a hundredths diagram:
each row shows one tenth each square represents one hundredth each tiny rectangle inside the square shows one thousandth,
Represent Thousandths on a Grid
Look at the diagram. There are seven rectangles shaded inside the first square. Which of these decimals represents the shaded part?
a) 0.7 b) 0.07 c) 0.007
Represent Thousandths on a Grid
Directions: Shade each grid to represent the given number.
0.2
0.15
Represent Thousandths on a Grid
Directions: For each diagram, match the decimal to represent how much is shaded. Write the correct answer on the line.
0.001 0.625 0.059 0.008
Represent Thousandths on a Grid
Directions: Shade 0.483 in the diagram. Be ready to explain or show your reasoning.
Represent Thousandths on a Grid
What number does this diagram represent?Where do you see 0.6 in the diagram? Color 0.6 green. Where do you see 0.02 in the diagram? Color 0.02 red. Where do you see 0.005 in the diagram? Color 0.005 purple.
Say What?
Four students look at the diagram and describe the shaded region in different ways. Which student is not correct? Why?
- Jada says it’s “15 hundredths.”
- Priya says it’s “150 thousandths.”
- Tyler says it’s “15 thousandths.”
- Diego says it’s “1 tenth and 5 hundredths.”
