6 times table space challenge

Children need so many opportunities as possible to practice their knowledge of tables and teachers are always looking for something else to maintain interest. Hopefully this page will be useful, since there is a bright and fun way to show how well the 6 times table is known and it can also be used as a timed challenge.

Beginning at the start moving to the first box, and write the number 6 time shown on the left side, then on to the next box, and so on. There are 20 questions at all; Some children can be ' stuck ' on a question, encourage them to go and then return to the end. If they are stuck remind them, for example, that if they forget 6 x 6 is the only six more than 5 x 6 which they must be able to remember.

This page can be found in our section math worksheets, multiplication four lines, and hopefully I will be adding similar pages for other tables times did not last long.

Source of the Week: 6 year mathematics challenge

Here is a bit tricky puzzle that is 6 years or upper juniors (9/11). Ideal for wet breaks!

Use only the digits 1 through 9 complete correct the number of sentences, both horizontally and vertically, so they all are.

A good knowledge of tables is needed, along with the ability to add and subtract mentally.

The hardest part of this puzzle is getting started and the best approach is to use process and improvement by picking one row or column that can have only a limited number of opportunities. This wouldn't be the first row or column down.

This particular puzzle to look at the first row is a x b – c = 34. Start by watching combinations of numbers that when multiplied, more than 34 (but no more than 43 if the maximum subtraction is 9) and then see what number can be subtracted to leave 34.

An important note about this: all calculations are done in the following order: Bodmas is not applicable.
