Grid Method / Place Value PowerPoint uses arrays and smiley faces to show the mental multiplication strategy of using place value and knowledge of multiplication to work out a 2-digit number by a 1-digit number - with exchange (such as 8 x 35, 9 x 33 etc.).

No text to read or get distracted by.

12 examples which build from 4 x 18 & 3 x 22 on the first two slides up to 9 x 33 & 8 x 83 on the last two slides.

All slides follow the same animations:
*Array and multiplication problem is shown.

  • Confused smiley bounces in (teacher explains that if you don’t know your 83 times table you’re going to be confused)
    *array changes to show place value calculations.
    *Confused face is replaced by a happy face as he can now do the multiplication problem.

12 examples clearly help grade 3,4 or 5 students master and understand this important skill.

With matching differentiate worksheets for multiplying 2-digit number by a 1-digit number.

This is an extremely well-designed PowerPoint that helped me clearly explain multiplication of larger numbers to my Year 4 students. My students liked the confused smiley faces and the step by step approach. Very useful.
