The jump from learning subtraction and addition to learning multiplication is one of the toughest tasks students will face at school.
We can generalize multiplication strategies to 4
- Repetitive Addition: Relate multiplication to addition.Avoid starting with memorization. Students typically struggle to memorize multiplication facts on the first try, and this can lead to a fear of the multiplication table. Example : 2+2+2+2+2 = 2*5= 10
- Equal Groups: Groups that have the same number of equivalent items.
- Skip Counting : Skip counting deals with counting by numbers other than 1, such as, by 2, by 3, by 5, 10 or 100. It helps in arithmetic calculations such as addition, subtraction and multiplication.
Example : Skip counting of 2 is 2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,…., so on
- Intersection of lines :Draw number of lines parallel. Once you have drawn the sets of lines, you can simply count intersections, and read off your answer.
