2 CUBE strategy exampleA taxi company charges a $3 set fee per ride plus 50¢ for each minute the ride lasts. The company uses the expression m to calculate the cost of a ride in dollars, where m stands for the number of minutes the ride lasts. [What is the cost of a ride that lasts 50 minutes?]
3 KNOC STRATEGY What do I KNOW (what is given) What do I NEED to know (question)What OPERATIONS are involved to solveWhat COMPUTATIONS are necessaryNote: students make four columns to record the information in.
4 KNOC strategy exampleThe 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 actionKnow (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)
