Year 3 mental arithmetic: Sets 5 and 6

This week I have the following two sets of mental arithmetic questions published for 3 years. They concentrate on one-step problems, recalling addition and subtraction facts up to 20, adding and subtracting multiples of ten and know 5 and 4 times tables.

There are several ways that these questions can be used and how children to answer them. It is sometimes a good idea to use a numeral cards, so that children can keep up the answer. Number of fans a similar goal. Sometimes you might want to be called the answers, or to be written. The sheets of the question can be used for this purpose.

Year 3 mental arithmetic Sets 3 and 4

Two sets of mental arithmetic questions suitable for 2 years. These sets of 10 questions relate to the count and back in dozens, addition, subtraction, and place value.

I have been asked for more in the way of mental arithmetic questions on many occasions and as the weeks go by this must be in a really useful resource. I'm also trying to match the questions to the primary framework for mathematics Planning, so this could be particularly relevant for the first few weeks of the autumn term.

Year 3 mental arithmetic: Sets 1 and 2

I'm embarking on something new this week which will hopefully to a really useful source will grow as time goes by. It is the first in a series of mental arithmetic questions aimed at 3 years.

It consists of two sets of ten questions, followed by an answer sheet. Each set is a full A4 page so they can be used in different ways. If given orally, the teacher/parent page-only the answer print, like all questions are included on this and the kids can just write the answers or call them out. If the teacher/parent wants the child to read the questions can then they print the question sheets as well. This can also be displayed on a whiteboard.

The first series of questions focus on writing integers, count on and back in the trans-European networks, addition, subtraction, and place value.

More year 4 mental arithmetic: subtraction

This is the second page of ' very difficult ' subtraction questions for year 4, that needs to be answered by using mental arithmetic methods, although many adults would struggle to achieve the correct answers: they are really very difficult!

Once again shows that there are different ways to set up each question; the key is to choose a method that efficiently and quickly. For example, they can be performed by counting, but this is also possible the quickest way and it's speed and accuracy that we are looking for.

It is also always a really good idea to check answers by performing the inverse operation; in this case would complement the answer and smallest number the largest number.

This, and other similar pages can be found in our year 4 calculations category even if the section four lines.
