Measuring with Color Tiles and Rulers

In this lesson, students learn to make and use a ruler with one-inch color tiles. The video covers creating color tiles, using them for measurement, and constructing a ruler. It emphasizes accurate measurement techniques, including aligning objects correctly and measuring longer items. The lesson concludes with a practical exercise and a preview of the next topic on estimating lengths.

What is the first step in making one-inch color tiles?

• Folding the paper

• Coloring the paper

• Marking one inch along each side of the paper

• Cutting the paper into strips

Why is it important to ensure there are no gaps or overlaps when using color tiles to measure?

• To save space

• To make the tiles reusable

• To ensure accurate measurement

• To make the measurement look neat

What should you do after drawing a line on one side of the color tile when making a ruler?

• Move the tile over and draw another line

• Cut the paper

• Color the section

• Measure the length again

When measuring an object, where should you line up the left edge of the object?

• With the middle of the ruler

• With the first mark on the ruler

• With the edge of the paper

• With the last mark on the ruler

How do you measure an object that is longer than your ruler?

• Estimate the length

• Use a longer ruler

• Mark where the ruler ends and move the ruler to continue measuring

• Cut the object into smaller pieces

What is the total length if you measure 6 inches with the ruler, move it, and measure another 4 inches?

• 8 inches

• 10 inches

• 14 inches

• 12 inches

If an eraser is measured to be less than 4 inches, what can you conclude?

• The eraser is not measurable

• The eraser is shorter than 4 inches

• The eraser is longer than 4 inches

• The eraser is exactly 4 inches

Why is it important not to count the lines when measuring with the ruler?

• The spaces between the lines represent the actual measurement

• The lines are too thin to count

• The lines are not accurate

• The lines are just guides

What should you do if the object you are measuring is longer than the ruler?

• Mark where the ruler ends and continue measuring from that point

• Estimate the remaining length

• Use a different measuring tool

• Measure only part of the object

What is the next lesson (8.3) going to be about?

• Drawing straight lines

• Estimating the length of an object by comparing it to something else

• Using rulers to measure objects

• Creating more color tiles
