How could you model 3 x 4? Model with Arrays How could you model 3
x 4? Model with Arrays You can also model 3 x 4 in an array. An
array is an arrangement of objects into equal ROWS. Model with
Arrays An array is an arrangement of objects into equal ROWS.
Examples of arrays: Model with Arrays An array is an arrangement of
objects into equal ROWS. Examples of arrays: Model with Arrays An
array is an arrangement of objects into equal ROWS. Examples of
arrays: Model with Arrays 3 rows of donuts An array is an
arrangement of objects into equal ROWS. 4 donuts in each row Model
with Arrays 3 rows of donuts This is an array with 3 rows (or equal
groups) of 4 donuts each. 4 donuts in each row Model with Arrays 3
rows of donuts We can write this 3 x 4 = 12 3 rows of 4 is 12 3
fours is 12 4 donuts in each row Model with Arrays With square
tiles, make 3 groups of 2. Model with Arrays With square tiles,
make 3 groups of 2. How would you write this as a multiplication
sentence? Model with Arrays With square tiles, make 3 groups of 2.
Turn this into an array. This is an array with 3 rows of 2 tiles
each. We can write this 3 x 2 = 6. Model with Arrays We describe
this as a 3 by 4 array because there are 3 rows with 4 tiles in
each row. 3 x 4 = 12 3 rows of 4 is 12 3 fours is 12 3 rows 4 tiles
in each row Model with Arrays Make as many arrays as you can with
10 square tiles. Record the arrays you make by writing the
multiplication sentence that corresponds to the array. 10 x 1 = 10
2 x 5 = 10 1 x 10 = 10 5 x 2 = 10 Model with Arrays To find the
product of 4 x 6, make an array with square tiles. Remember: 4 rows
of tiles, with 6 tiles in each row To find the product of 4 x 6,
count up all your tiles. 4 x 6 = 24 Game: How Many Rows? How Many
in Each Row? DIRECTIONS: Roll the dice One die is the number of
rows; the other is the number in each row Draw the array on your
grid Write the multiplication equation inside the rectangle The
player with the most squares covered wins Exit Ticket Match the
array to the equation. 3 6 = 18 4 3 = 12 2 6 = 12 1 12 = 12 5 6 =
30
