Tuesday – I was out of the classroom attending the Kentukcy Mathematics Leadership Network Training.
2/22/11 Targets 2 & 4 Blue TEXT pages 165-166 “Let’s Bowl” In class.
Q#1 the ordered pair is (3, 10.50) which represents 3 games bowled, it will cost $10.50. Yes the situation does represent a relation (any set of ordered pairs) since you can represent the games and cost as ordered pairs.
Q2 The relation is a function b/c for each number of games bowled, there can only be one cost.
Q3 f(x) = 2.25 + 2.75x
Q4 you multiply the number of games bowled by 2.75, then add 2.25, the cost of shoe rental
Q5 answers are 7 20
2/22/11 Targets 4 & 5 Family Values of Functions wkst. Calculate Function Values for given domain; Record results in Table of Values.
2/22/11 Target 5 Plot points from Function Values wkst to create graphs of the functions.
In class: Checked & discussed pages 165-166; formative assessment showed many students were lacking on correct calculations involving absolute values…we did 3 examples, comparing the equations & resulting range values.
Assignment to go back over Tables of Values and make corrections as needed. Redo / check corresponding graphs.
In class: Target – To correctly enter a function into graphing calculator and see the resulting graph.
4 examples were demonstrated as “we do” problems: Immediate formative assessment looking at student screens; correct any errors from invalid dimenstion to sytax errors.
Thursday – Students will work in small groups to complete an investigation focused on Unit Learning Target #6.
