**KNOC STRATEGY What do I KNOW (what is given)**

What do I NEED to know (question) What OPERATIONS are involved to solve What COMPUTATIONS are necessary Note: students make four columns to record the information in.

4
KNOC strategy example The distance around a track is ¼ mile. Sheila runs 9 miles each day. So far, she has run 5 miles around the track. How many more times must she run around the track to complete here 9 miles?

5
KNOC in action Know (1 time around is ¼ of a mile…she runs a total of 9 miles…she has ran 5 miles so far..she has 4 miles to complete) Need (How many more times around the track equals 4 miles) Operations (subtraction, division, multiplication, addition is also possible) Computations (9 miles - 5 miles= 4 miles left… ÷ ¼ = 4 x 4/1 = 16) or (1 mile = ¼ + ¼ + ¼ + ¼ or 4 times around, therefore 4 miles X 4 times around = 16 times around)
