I made this sheet to assess students' understanding of place value. The different math concepts measured by this quiz include base-ten theory (10 times greater & less, etc.), place value, value, comparing numbers, and reading and writing numbers in word form, expanded form, and standard form. There are 18 questions on the quiz, and I score it out of 20 points.

I made this presentation to help teach divisibility rules and prime and composite numbers. The show starts with a warm-up that requires a hundred chart. Students use the chart to identify composite numbers, and in the process uncover prime numbers. The following slides guide students through a review of multiples and factors and the discovery of divisibility rules.

I made this sheet to help reinforce with my students the idea that "in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right."* The worksheet has students calculating 10 times more or 10 times less than a number for several numbers. Students are then asked to analyze their responses and record what they notice. I allowed my students to use a calculator, if they needed to, to complete the calculations because my focus was on their ob

I made this presentation to help introduce/reinforce the concept of rounding to my students. There are 9 slides in the presentation, and it walks students through what is rounding and how to round. Much of the show is based on a rounding example where students explore rounding a number to different places. The show features motion and has built-in stopping points to allow for discussion. What you see in the screenshots will not all display at once when you play the show. It ends with severa
