The concept in this free math tutoring video is slightly easier than talking about tens because we call numbers in the hundreds place, hundreds. This is not the case with the tens place. We say “twenty,” not “two-ten” or “thirty,” not “three-ten” as they do in other countries. Working on naming a certain number of hundreds when they add up to more than one thousand is the important concept here.
This free math tutoring video shows an important concept to understand for place value, the distributive property, and long multiplication and division. Start small and, over time, work your way up to the type of problem we did at the end. Let children figure out the pattern for themselves by using the Cuisenaire Rods to actually SEE how you are just jumping up to the next decimal place.
This free math tutoring video shows an important concept to get down, especially for when it comes time to do long multiplication or division. Lots of practice in giving the “real” names for a certain number of tens or telling how many tens is in a number is essential for understanding more complex elementary school math.
Cuisenaire Rods help make the concept of place value, which is often very abstract for children, more concrete and understandable. They can visualize it. They can feel it. They can much more easily internalize the concept.
