What This Standard Means
What Students Need to Do
- With help, children ask a question about saving paper or another resource. They compare two ways to use it, then show what happened with counts, drawings, or words.
What Mastery Looks Like
- A child can ask, 'Does drawing on the blank side save new paper?' They follow the class plan, count the new sheets used, and use that count to explain their answer.
Common Misconceptions
- Some children think reducing means putting something in a recycling bin. Others call drawing on the blank side of a sheet recycling, or think every used item can be recycled.
How to Assess It
- Give pairs three new sheets and three used sheets with blank backs. Help them ask which pile saves new paper, then have them draw on both piles, count new sheets used, and tell you what they found.
Lesson moves
Ways to Teach It
Give pairs three new sheets and three used sheets with blank backs; have them draw on each set and count new sheets used.
Ask, 'Should we draw on the blank back of a worksheet or put it in the recycling bin?' Have children explain their choice.
Show picture cards of taking one napkin instead of three, drawing on a used sheet, and recycling a clean bottle; children match reduce, reuse, recycle.
At snack, count paper napkins taken today; tomorrow, try taking one per child and compare the totals on a class chart.
