learning times tables by rote

this chart was introduced to me by Roy Lindsell who, I believe, created this idea

these are (nearly) all the products that need to be learned
all of the factor pairs involve digits - so there are no 1s and no 10s etc.
so 40 is not  4 x 10, nor 2 x 20;  it is  5 x 8

learning tables 'backwards': from the result, give the product
e.g. when 14 is tapped on, a student or students say "2 times 7"
in the interests of communal class chanting (only) get students to say the smaller number first
e.g. 42 is  6 x 7

where there are two numbers, say the one with the smaller factor first
e.g. the first 18 is  2 x 9 and the second 18 is  3 x 6

square numbers are shown appropriately

this can be a whole class chanting activity, anytime during a lesson

someone taps on a number (maybe the teacher) and students call out the two numbers that form the products

done a section, a row, at a time (initially)
building up confidence before moving on

learning things by rote can be managed by small and often bursts (distributed practice)

having an enlarged version stuck to the wall enables repeated practice to happen

done a bit at a time
getting confidence developed with one row then going on to another one
still returning to the original rows(s)
jumping around, increasingly randomly
and getting faster


the following powerpoints work on a particular times table
(they need to be downloaded for the animations to work)




















the ppts introduce the various products first
then, once the results are there, someone can tap on these end points and a group of students/the class call out the multiplier

e.g. if it's the 5 times table and 35 is tapped on, the multiplier (to be called out) is 7
there are several versions for each times table, so that students don't just get used to where things are located

there is a worksheet at the end of each ppt, on that particular times table

2 times table
3 times table
4 times table
5 times table
6 times table
7 times table
8 times table
9 times table
mixture
