Need your students to practise written methods for multiplication but tired of just giving them a worksheet to complete? Look no further because included in this package are 28 tasks cards each with 2 spot the mistake tasks to engage, enrich and extend understanding of the grid method and formal written methods for:
THHTU x U, U.th x U, TU x TU, HTU x TU, THHTU x TU and U.th x TU.
There are 8 tasks for each type of method so work can differentiated across the class depending on their ability and understanding of the different written methods. They could also be used into conjunction with manipulatives and resources.
The task cards have been made so that they are easy to photocopy and use.
They could be enlarged for those who need more space for their writing.
They could be used as an activity for individuals or students could work in a group of 4 and each complete the first box and then pass to the person on their left, complete the next section and pass again until all the sections are completed. The first box could be used just on its own and students just spot the mistake and write the correct answer in their books – the possibilities are endless!
Answers have been included.
