Understanding Arrays and Skip Counting

This video tutorial teaches how to read arrays using skip counting. It begins by addressing common misunderstandings about arrays, such as the inability to create an array of sevens using twos. The tutorial then provides examples using arrays of cats and X's, demonstrating how to write equations and use skip counting to find totals. The lesson concludes with a summary of the key concepts covered.

What is a common misunderstanding when creating arrays?

• Arrays must always be even.

• Arrays can be made with any number.

• Arrays must have equal add-ins.

• Arrays can be made with any number of rows.

How are rows oriented in an array?

• Diagonally

• Vertically

• In a circle

• Horizontally

In the cat array example, how many columns are there?

• Six

• Four

• Three

• Five

What is the sum when skip counting by fours in the cat array?

• 16

• 24

• 20

• 28

How many cats are in each row of the cat array?

• Three

• Four

• Five

• Six

In the X's array, how many rows are there?

• Four

• Three

• One

• Two

What is the equation for the X's array using columns?

• Four plus four

• Five plus five

• Three plus three

• Two plus two

How many X's are there in total in the X's array?

• Seven

• Six

• Five

• Four

What is the sum when skip counting by twos in the X's array?

• Ten

• Six

• Eight

• Four
