Array Museum

For Math Chapter One, students were asked to bring in household items that contained an array. In an array, each row contains the same number of objects, and each column has the same number of items. Several students took advantage of this extra credit opportunity. Can you write a number sentence for the following arrays?

Number 21 brought it an egg carton (2 rows, 6 columns), crayons (3 rows, 8 columns), and water bottles (3 rows, 2 columns).

Number 24 brought a paper game (2 rows, 2 columns), Number 28 brought in a plastic peg board (14 rows, 14 columns), and number 7 brought in a Lego array (2 rows, 4 columns).

Number 20 brought in a cupcake array (4 rows, 6 columns), but it didn't last long enough to be a part of our museum! Yum!

Number eight brought in a paint pallate ( 3 rows, 8 columns).

Number 4 brought in an array of letters ( 5 rows, 4 columns).

Write a number sentence for one of the arrays to recieve extra credit. Make sure to say which object you are writing it for.

Quizzes and Going Green

Throughout the school year our class will be taking Math Quizzes to check our understanding. In an effort to "go green", quiz questions will often be given orally or shown on the overhead projector. Students will write their answers on scrap paper. If you would like to know what was asked, check our blog. I will post the questions as well as the sections they cover. It might also be a good idea to review these questions before the chapter test. Having them on the blog will make access to this review tool simple. Below you will find the questions for our first math quiz of the year. Happy Quizzing!
