  2. 28x 24 The Alcova cafeteria has twenty eight tables. If 24 students are sitting at each table, how many students are sitting in the Alcova cafeteria?

  3. 24x 28 Then we can break apart our numbers by place value– tens and ones. First, let’s make our window. We have two digits in both numbers, so we should have 2 rows and 2 columns in our window. 20 4 20 8

  4. Row x Column What is 20 x 20? 400! What is 4 x 20? 80! Remember.. If you know your basic facts, you can use patterns to help you figure out how to multiply larger numbers with zeroes! 20 4 Now we can multiply to find the product for each square. We multiply each row, by each column. 20 8 400 80 160 32 What is 20 x 8? 160! What is 4 x 8? 32!

  5. + + 20 4 Next step: Add up the squares in the same column OR row. 20 8 400 80 400 + 160 560 80 +32 112 + 160 32 560 + 112 672

  6. We found our answer! + + 20 4 20 8 400 80 400 + 160 560 80 +32 112 672! + 160 32 560 + 112 672
