Lea rnin g Ta rget 2: Use and explain strategies to solve addition and subtraction basic
fact problems (e.g., doubles plus one, make a ten) and word problems (e.g., direct modeling).
Des c rip to rs:
B.b:6 Use and explain strategies (e.g., direct modeling, counting, numerical reasoning) to
solve a variety of addition and subtraction word problems (e.g., change unknown,
comparison, part-whole) and write number sentences that match the structure of the
problem
B.b:7 Use numerical reasoning or number relationships (e.g., 8 + 5, first add 8 + 2, then
add 3 more) and counting strategies (e.g., 7 – 5, start at 5, count up to 7, keep track of
the counts) to solve addition and subtraction basic fact problems.
Skills Assessed: Counting on or back strategy, word problems, writing equations to match pictures,
