Math-Partition A Rectangle

 We finished our study of cubes and focused on the number of equal faces. We built cubes out of gum drops and toothpicks and created a paper cube. Now, we have moved our studies to the following standard:

2G.2 Partition a  rectangle into rows and columns of same-size squares to find the total number of them

Today, we used 12 square tiles and built as many different rectangles as we could using the total of 12. We discussed the different arrays and how many tiles were in each row and column. Then, we discussed using repeated addition to explain the number of tiles in each array.

total-15 tiles in the array

3 rows

5 columns

total-21 tiles in the array

7 rows

3 columns

When recording our work in our journals, we have focused on attending to precision, look for and make use of structure and look for and express regularity in repeated reasoning- which are Standards 6, 7, and 8 of the Standards of Mathematical Practice
