FAQ
In what order do 1st graders solve expressions with 3 numbers?⌄
Students work from left to right, performing each operation in sequence — the same left-to-right rule they will use for all arithmetic until order of operations is formally introduced.
What strategies help 1st graders add and subtract three numbers?⌄
Looking for combinations that make 10 first, or grouping numbers that are easy to add, can simplify the computation before subtracting the third number.
Is adding and subtracting three numbers part of 1st grade standards?⌄
Yes — CCSS 1.OA.A.2 expects students to solve problems involving three whole numbers whose sum is no greater than 20.
