Fourth graders are practicing addition and subtraction with regrouping. They are now manipulating multi-digit numbers. They are also practicing checking their work and looking to see if their answer makes sense. Strong learners always check their work and look at the problem to make sure the answer makes sense. They are also finishing their green bin audit posters adding data to their poster.
Learners began using tape diagrams to explore word problems. We looked at variables and discussed how we can use variables to solve unknown numbers. We are also reviewing fact families with fourth grade. Learners are working toward being able to fluently add and subtract large numbers with regrouping. Regrouping is what is what we used to call "borrowing." They are also continuing their Trimester 1 project which is their green bin audit project which explores composting.
