Primes, Squares and Cubes

£10.00
SKU M5CS42000

Revisit the children’s understanding of square and cube numbers in the context of area and volume. Then move on to exploring the definition of prime and composite numbers and their properties.

 
#TheCompleteSeries5lessons

Investigate the building blocks of every number by finding their prime factors and consolidate the children’s knowledge of squares, cubes and primes when recording the multiplication sentences of prime factors and in problem-solving activities.

#Lesson1AreaandSquareNumbers

Revisit area and square numbers with your class and begin to use square numbers in context with the formula: length x height. Remind your class of the notation for square numbers and use this understanding in different problem-solving calculations involving square numbers and area.

  • Lesson plan
  • Slides
  • Activity ideas
  • Differentiated worksheets
  • Challenge cards
#Lesson2VolumeandCubeNumbers

Revisit the formula for finding the volume of a cuboid: length x width x height. Use this opportunity to bring cube numbers into context with your class when looking at the units and notation when referring to volume. Challenge the children to use this knowledge in a range of problem-solving activities involving cube numbers and volume.

  • Differentiated worksheets
#Lesson3PrimeNumbers

Help your class discover and identify prime numbers and their properties. Encourage them to use the language of prime and composite numbers by investigating their factors and grouping the numbers together. Help them investigate which numbers are prime up to 120 through the use of Eratosthenes’ sieve and other prime number investigations.
