Notes | Blocks and tiles for integers. The visual students really liked this. It helped them immensely. The algebra students that remembered it from last year didn’t want to go back to the visual part. It actually confused some of them, especially neutralizing with the subtraction. I resort to them quite often when I see a bit of confusion in the students’ eyes. They work nicely with positives and negatives. Today with multiplication of negatives the students got a little confused. They wanted to know ‘why’ the positives and negatives were arranged the way they were on the grid. |

Notes | My pre-algebra classes were learning to add like terms yesterday. I usually introduce this with M & M's, but forgot to get them, so I thought I would try the Algebra tiles. I used the different color tiles to represent different variables laid out the terms and then had the students write the expression and simplify it. They seemed to grasp the concept of "Like terms" better than with the M & M's. Some of my students, who have been struggling, were answering questions right and left...apparently they like the visual!! |

Notes | I used the two colored tiles in my Algebra 1 class. The students were showing the addition and subtraction of integers with the tiles. I did not discuss the rules first but some of the students wanted to state the rules instead of showing the addition/subtraction. This process reinforced the subtraction rule of changing to add the opposite. The students also remembered being introduced to subtraction as “take away.” This activity was great for the visual learner – which I think I tend to overlook in my classroom because I am not visual. |
