Primary 4 – Expressions and Equations

We have been working really hard on our maths tasks linked to Expressions and Equations.  We have been finding out how to use the symbols for greater than and less than when comparing two numbers.  Some of the children have been learning how to solve  simple equations by working out the value of a letter, such as n or x.  Some examples of these equations:

n +6 = 15  so  n = 9               73 – n = 49 so  n = 24

We also designed our own Expressions and Equations posters to help us to remember the symbols.
