Count in 4s and 8s

4 8 12 16 20 24 28 32 36 40 44 48 ...

 

8 16 24 32 40 48 56 64 72 80 88 96...

 

We know the tables above are x 4 and x 8

We need to know these facts in order to count in 4s and 8s.

 

16 20 24 28 32  --

We can see that the pattern here is adding 4.

The following number will be 36 (32 + 4)  

 

32 40 48 -- 64 72

We can see that the pattern here is adding 8.

The missing number will be 8 more than 48 (48 + 8 = 56)

The missing number is 56

 

Now, let's use counting in 4s and 8s to solve a word problem!

 

 

Pencils come in boxes of 8.

Connie has 3 boxes of pencils;  she has 24 pencils (3 x 8 = 24)

She buys 1 more box.

How many pencils does she now have?

24 + 8 = 32

Connie has 32 pencils.

 

 

Now why don't you have a go at counting in multiples of four and eight? 

 

The numbers may get higher, but just continue to count on in either 4s or 8s!

 

72  76  80  84  88  92 ....

 

88  96  104  112  120  128...

 

Good luck!
