Andrew's parents follow a regular schedule for taking care of their car. They change the oil every 3 000 km, rotate the tyres every 10 000 km and replace the wiper blades every 15 000 km. After how many kilometres will they first have to change the oil, rotate the tyres and replace the wiper blades all at once?Β

Describe in mathematical terms the four transformations applied to the graph of y=x^2 in order to get the graph of y=-2(x-7)^2+6
1 1/4 / 2/3
Draw and shade vertical columns for 1 1/4
Make two thirds with circles
Mark the vertical shaded blocks with X
The X is the numerator of the answer.
Solve the fraction below using number line
1. 4 2/3 / 1 1/6
2. 1 1/4 / 2/3
3. 2/5 / 1/3
4. 3/4 / 5/6
2. Cut out the strip and place it on the fraction strips (see appeadix 2.5 (not 3.5)
3. Check to see which unity fractions the strip of the sum of 1/2 and 1/3 fits perfectly.
4. If it fits perfectly with more than one of the unit fractions, which ones are those and why does it fit perfectly with them?
Example: Grade 4patterns, functions and algebra. Conceptual understanding, procedural fluency, strategic competence, adaptive reasoning and productive disposition. How will i teach this example in grade 4 patterns, functions and algebrato ensure competency?
