Hands-On Doubles and Halves Activities for Elementary

A fundamental concept weaved throughout any math standards is the idea of doubling quantities and halving quantities. Though not explicitly stated often it is implied in most strands. It functions as a good rule of thumb for orienting numbers.

Hands-On Doubles and Halves Activities for Elementary

Math comes to us in picture, word, and numbers. I taught Hispanic at risk students grades K - 5 and discovery this was a fundamental gap in our math teaching. Many standards have a basis in doubles and halves. It is benchmark numbers for mental math. Teaching this intentionally raised many students scores to near passing. This lesson for doubling uses mirrors giving a visual representation of double and the book Two of Everything is available on Youtube https://www.youtube.com/watch?v=WdmI32qY_c

Here is what doubling becomes in Jr. High. I did this story with at risk 5th graders scaffolded to prepare them for algebraic reasoning and language in when they graduated. http://jwilson.coe.uga.edu/EMT668/EMAT6680.F99/Martin/instructional%20unit/day4.exponential/excel/grainofrice.html

Math has a specific language and it has to be specifically taught. Here is the Common Core language used in standards and on tests. Teach it and it prepares students for higher mathematics.There is nothing worse than having a student who made A's in elementary go to 6th grade and fail. I got the honor of visiting with 6th grade students that it had happend to. What they would tell me over and over again was Mrs. Page I did not understand what it asking. I investigated.

This video is application level of the concept of doubling used for multiplication. I had many students who worked harder than the others to memorized facts and the facts would fade if not reinforced everyday. The child and I would grieve. One day I decided that the teaching was wrong for that child's brain. I went and found other ways to know your facts. Asian math programs have other techniques and it worked with these children.

Research on Numeracy

Mary Page says:
Teachers hear me now---Math is a system of relationships to investigate and understand not a collection of rules. This article explains the difference and shows how to do a number talk. It shows how to create benchmark numbers in a child's schema. Most of all it shows how children can develop math talk between each other internalizing for future use at the high school level. Math language in the general public and on media is not common.
