Subject: Using manipulatives to teach multiplication
I have use counters of different colours to teach multiplication to grade three and it works. I told them that a red counter represent one group of ten and blue counter represent ones. so first of all give them a mixture of counters and ask them to call out the number it would represent. For example 3 red and 5 blue would be 35. then ask them how many tens and how many ones are in your number. allow stdents to write their numbers as 30+ 5 =35 when students are able to expand their numbers then more into the process of multiplication. 35 x 3 = 30 x 3 + 5 x 3 90 + 15 allow students to use three rows of three red counter + 3 rows of 5 blue counter. let them count the red counters as 10, 20,30 etc. Be patient with them and as they ubderstand the concrete then you can move away to the abstract.
