Third grade students visited Mr. Bulaevsky's website - Integer Bars - and had fun using his colored bars to make sums - only one of many possible math lessons using this applet.
In the first activity the students were told to find as many ways to make the sum of 8 using exactly 3 integer bars. At first this was a challenge for some but they eventually arranged their integer bars on the screen to total the number 8. After the students arranged "number trains" using 3 bars to make a total of 8, they were challenged to make as many "number trains" as they could using only 4 bars to make the number 10. Math class flew by in a flash and the students did not have time to write the number sentences for their "trains." Mrs. Weeg printed their work (using a print screen capture) and the next day the students wrote number sentences for each train that equals the desired sum. |
