1.) Students will practice building rectangular arrays for multiplication facts. Using blocks or square tiles, students will take a fact such as four times three and build an array that is four tiles wide by three tiles high. When the rectangle is completed, it contains twelve squares.  

2.) For each set of multiplication facts students need to study, they will use graph paper or build with square tiles or blocks and record all the relevant multiplication and division facts about it: 4 x 3 = 12; 3 x 4 = 12; 12 / 4 = 3; and 12 / 3 = 4. They could draw the arrays in their Mathematics Journals or cut them out of graph paper and paste them into their Journals. 

1.) When given a number, students will be able to write the multiplication and division facts that relate to that number, such as the number 20: 1 x 20 = 20; 2 x 10 = 20; 4 x 5 = 20; 5 x 4 = 20; 10 x 2 = 20; 20 x 1 = 20; 20 / 1 = 20; 20 / 2 = 10; 20 / 4 = 5; 20 / 5 = 4; 20 / 10 = 2; 20 / 20 = 1
