This unit shows how to use partial products to multiply. I's easy to recall products of 2 and 5, so we can use them as building blocks to find products of 3, 6, and 7.  The unit includes 3 videos to demonstrate the build up strategy using factors 3, 6, and 7. Easel Activity with self-check so students can practice and explore the strategyPrintable Papers to apply learning in fact recall. ✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦ The Build Up strategy uses partial products to multiply.  Whe

In this final video of the Build Up series, we use the build up strategy to multiply by 7. We start with a bar model then use an equation to demonstrate that 5 groups + 2 groups = 7 groups. ✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦The Build Up strategy uses partial products to multiply.  When students use alternative strategies, they  develop flexibility with numbers that help them become more fluent mathematicians and more flexible problem solvers.

The second of 3 titles in the Build Up to Multiply series, this video demonstrates how to multiply by 6 using partial products. Bar models demonstrate how 5 groups plus 1 group equals 6 groups. The strategy is demonstrated with single digit and double digit factors. In the first video, we used coconuts as a pictorial representation. In this second video, the use of pictures has evolved to enhancements rather than counting tools. Bar models are used to represent ✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦

This is the first of 3 videos in the Build Up series. Using a double and a single to multiply by 3 is a fairly simple task that sets up the foundation of multiplying with partial products. ✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦The Build Up strategy uses partial products to multiply.  When students use alternative strategies, they  develop flexibility with numbers that help them become more fluent mathematicians and more flexible problem solvers.

This free resource from WhiteBoard Math uses elephants and a few truckloads of peanuts to divide with the standard algorithm.  We start by defining division terms: dividend, divisor, quotient, then demonstrates, step-by-step, dividing into a 4-digit dividend.  As with other WhiteBoard videos, the content starts simple then progresses towards more complex thinking.   This is our  free product because so many teachers are  looking for a good video on how to do “long division”.  Your students will

This doubling unit shows how to easily multiply by using doubles.   Double once to multiply by 2  Double twice to multiply by 4  Double three times to multiply by 8   The unit includes: Video demonstrating the doubling strategy using factors 2, 4, & 8Easel Activity with self-check so students can practice and explore the strategyPrintable Papers to apply learning in fact recall. ✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦✦ This alternative strategy helps us with basic multiplication and can be
