Measurement test feedback

Measurement test feedback

by Tessa Gould

​Check Showbie for your raw score and individual feedback from the topic test.

​Note: these are raw scores and may be subject to scaling

​Strengths

• ​Working out was neat clear and easy to read

• ​Volume question 8 was done well

• ​Conversion between units was done well

• ​Students gave answers correct to required number of decimal places

• ​2D diagrams were drawn to help understand a 3D space

​Areas of improvement

• ​Include all units, even when the answer is an exact value

• ​Remembering formulas correctly - understanding the formulas

• ​Calculating surface areas of irregular shapes

• ​Think about how CAS can be used to help you work faster or check answers

• ​Some people entered their answers sideways and I got a sore neck marking

Poll

What should we do in class on Monday?

• Application/revision

  Pro: time to study and ask questions before the AT

  Con: Won't be able to start 8B until next Friday

• Start 8B

  Pro: More class time for 8B

  Con: Less class time to prepare for the AT

Poll

Do you want to do the practice AT on exam.net or would you like a PDF copy?

(You will get solutions for either option)

• PDF

• exam.net

​Rest of the lesson - tasks

Must do:

• Respond to your individual feedback on showbie​

• Finish textbook work, either chapter 6 review or 8A

• ​Should do:

• ​AT revision questions - on showbie and google classroom

• ​Practice AT
