Introduction to Multiplication and Tables: Class 2 Study Guide
Multiplication is a quick way to add equal groups. Tables are lists of those facts.
If there are 3 plates with 4 pakoras on each, the total is 4 + 4 + 4 = 12. We write this as 3 × 4 = 12 and read it 'three times four is twelve'. The × sign means 'groups of' and the answer is the product.
In Class 2, children learn tables of 2, 3, 4, 5 and 10. The best way is to use patterns and real things: pairs of shoes for the table of 2, wheels of tricycles for 3, legs of chairs for 4 and fingers on a hand for 5.
Making equal groups
Draw or arrange objects in equal groups, then count the total. Equal groups can be shown in rows and columns, which is called an array.
Tables patterns
| Table | First five answers | Pattern |
|---|---|---|
| 2 | 2, 4, 6, 8, 10 | Even numbers; double the number |
| 5 | 5, 10, 15, 20, 25 | Ends in 5 or 0 |
| 10 | 10, 20, 30, 40, 50 | Add a zero |
| 3 | 3, 6, 9, 12, 15 | Add 3 each time |
| 4 | 4, 8, 12, 16, 20 | Double the table of 2 |
Learning tables well
Say them aloud, forwards and backwards, and fill in missing numbers. Use skip counting on a number line or hundred chart. Remember that order does not change the answer: 2 × 5 = 5 × 2 = 10. Use known tables to find new ones: the table of 4 is double the table of 2.
3, 6, 9, 12…
Three fours are twelve.
3 × 4 = 12.
Draw 3 rows of 4.
Worked examples and common mistakes
Example: 5 boxes have 3 pencils each. 5 × 3 = 15. Example: 4 × 10 = 40. Common mistakes: adding when the problem says 'groups of', mixing up 5 × 2 with 5 + 2, and losing count when skip counting. Use fingers or a number line to keep track.
Check your understanding: model answers
1. 3 × 5 = 15. 2. 4 × 5 = 20. 3. 6 × 10 = 60 sweets.
