Presentation Transcript
C U B E STRATEGY
• Circle the numbers
• Underline the units
• Bracket the question
• Eliminate unnecessary information
CUBE strategy example
• A taxi company charges a \$3 set fee per ride plus 50¢ for each minute the ride lasts. The company uses the expression 3 + 0.5m 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?]
KNOCSTRATEGY
• 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.
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?
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… 4 ÷ ¼ = 4 x 4/1 = 16) or (1 mile = ¼ + ¼ + ¼ + ¼or 4 times around, therefore 4 miles X 4 times around = 16 times around)
