Drilling multiplication tables of 4, 11, and 9

This is an example of how to drill the multiplication tables of 4, 11, and 9, as explained in the guide How to memorize multiplication tables. Please refer to the guide first to understand how the structured drill works.

This drill is based on first memorizing the skip-counting pattern for a particular table. Students then practice associating those numbers with the facts from the table. As the last (and very important) step, students practice the table 'backwards'; in other words, they are given the "answers" from the table and asked how many times the number produces those.

Also, After each table, the student completes a 12x12 grid which has those facts blocked out that aren't studied yet. Each time, the blocked squares get fewer and fewer. These ideas are taken from my book Math Mammoth Multiplication 1.


Multiplication table of 4

Count by fours:    0, 4, 8, ___, ___, ___, ___, ___, ___, ___, ___, ___, ___

Fill in THE MULTIPLICATION TABLE OF 4.  You need to memorize these facts.  Cover the answers in the table with one hand and try to remember them!  Also practice them orally with your teacher.

1 × 4 = _____

2 × 4 = _____

3 × 4 = _____

4 × 4 = _____

5 × 4 = _____

6 × 4 = _____

7 × 4 = _____

... the table of four and table of three? _______________
... the table of four and table of ten? ________________

Drill

1.  Count by fours - up and down.  Cover a list with your hand and repeat it in your head (or to your teacher) until you can list the numbers easily.  You can first work with the first half of the list, then with the second half, and lastly do the whole thing.

0, 4, ___, ___, ___, ___, ___, __, ___, ___, ___, ___, ___

48, ___, ___, ___, ___, ___, ___, ___, ___, ___, ___, ___, 0

 
 
2.  Multiply - but only in your head.  Do NOT write the answers down.  Go through the problems until you master them easily.

5.  Solve the problems.  Remember to write number sentence(s) for each.

a.  The cheap socks cost 1 dollar each pair, and the expensive ones cost 3 dollars each pair.   Which takes less money: to buy 10 pairs of cheap socks or to buy four pairs of expensive socks?





b.  How many pairs of cheap socks can you buy with 15 dollars? 

How many pairs of expensive socks can you buy with 15 dollars?




e.  You see chickens and cats walking on the yard and they have total of 22 legs.  How many cats and how many chickens are there?

 




f.  Find two other solutions to the problem in e.
