Looking for a kid-friendly way to help your fifth graders practice using exponents to represent powers of ten? When I first saw that I had to teach the use of exponents to denote powers of ten, which is part of the Grade 5 Common Core Math Standards, most of the materials that I found were aimed at middle- and high-schoolers. I needed resources that were clear, engaging, and developmentally appropriate for my elementary-age students, so I designed the materials in this set to fill that need. The 32 task cards will allow your students to practice exploring with varied representations of the powers of ten. Extend your students’ practice (or assess their mastery of powers of ten) with the included activity sheets. With these resources, your students will grow stronger in their understanding of the different ways to represent powers of ten.
Common Core State Standards for Mathematics addressed:
Numbers and Operations in Base Ten (5.NBT)
Understand the place value system.
• Use whole number exponents to denote powers of ten. (5.NBT.2)
• graphic reference sheet
• 32 task cards
• answer sheet and key
• two one-page activity sheets (scoring guides included)
The printables consist of a full-page graphic reference sheet and two different one-page worksheets. The reference sheet (provided in color and grayscale) defines “powers of ten” in a variety of ways and illustrates the different ways to represent powers of ten – standard form, using a multiplication expression, using exponents, and word form. Before you have your students complete the cards, you can have them glue the reference sheet in their journals. They can fold it in half and glue it across two pages or glue half down to one page and fold it open to read. Have your kids use the journal insert as a guide while they work on the cards, as well as when they complete other tasks that relate to powers of ten.
The 32 cards feature a variety of question types to help build your students’ flexibility when thinking about powers of ten. Check out the preview to see some examples of the kinds of questions your students will see on these task cards. [Naturally, there is an answer sheet and a key included!]
The two provided worksheets can be used to evaluate student understanding of powers of ten. The worksheets are formatted similarly, and have similar types of questions, though the numbers on each are different. You can use these activity pages in a variety of ways. You could give one as a pre-test, then teach your lesson and allow students to practice with the task cards, and then give the second worksheet as an independent post-test. You could also have the students work on the task cards, then complete one of the worksheet as guided practice with yourself, a partner, or a small group, and then give the second worksheet as an independent assessment. The worksheets could also be given as homework, center assignments, or any other purpose that fits your teaching style or classroom routines.
