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. The students were told to find as many ways to make the sum of 8 using exactly 3 integer bars. When class time was almost over I made a screen capture of the number trains the students had made and pasted the image into Windows Paint. Once the images were in Paint the students could use the text tool to write number sentences below their integer bars. David was not finished when our class was over. There are some mistakes that need to be corrected in class tomorrow on the printed version I made for each student.
