Today we start our unit on expressions! Students explored that the big difference between expressions and equations is that expressions do not have an equal sign. Take a look at the examples below:
A expression would be:
5a + 7
An equation would be:
3a - 9 = 12
See the difference?!?
Students also explored how the expression b + b + b + b can also be written as 4b. Pretty cool, isn't it? We will keep working with expressions during this whole unit. Students will investigate with exponents, addition, subtraction, multiplication, and division in expressions and will also have a chance to evaluate some tricky expressions like they have seen in Study Island. We will be busy in sixth grade for this unit!
