Division Using Number Line Lit

這個數字線方案將幫助學生理解分工。

This program uses the number line to help the student understand division. For instance, if the problem is 12 ÷ 3 =, the program will tell the student click the 12 on the number line. Then it will tell him/her to start at 0 and count 3 spaces to the right and click on that number. The program will tell the student to keep moving 3 spaces to the right and clicking on the last number until he/she reaches number 12, and then click the “Done” button. The answer (4) moves up into the missing space in the number statement, and the program voice says “Yes twelve divided by three is four”
