| 00:00 - 00:05 | So we wrote the 2020 Standard 2 exam |
| 00:05 - 00:07 | Our second go at the new syllabus |
| 00:07 - 00:10 | First time with common content |
| 00:11 - 00:16 | So, we decide to have a bit of fun |
| 00:17 - 00:21 | Let's do a question about crickets! |
| 00:21 - 00:24 | A whole page of information before the question |
| 00:29 - 00:31 | Throw a box plot in there, they barely even use it! |
| 00:31 - 00:34 | Make them find the average temperature from the median! |
| 00:38 - 00:40 | Median.. |
| 00:41 - 00:47 | And the average of the chirps! |
| 00:47 - 00:50 | And then substitute into part of the least squares formula! |
| 00:50 - 00:56 | Substitute again, if they spotted the chirp average |
| 00:58 - 00:59 | Solve for b |
| 00:59 - 01:01 | And then get their answer! |
| 01:04 - 01:06 | 5 Marks |
| 01:06 - 01:08 | Completely unscaffolded |
| 01:13 - 01:14 | |
| 01:14 - 01:16 | They've never seen anything like it! |
| 01:16 - 01:20 | They've never seen anything like it! |
| 01:21 - 01:27 | And that's only the start of the fun. |
| 01:35 - 01:36 | Might do some disguised series questions |
| 01:36 - 01:39 | Might do some disguised series questions |
| 01:41 - 01:44 | But first, let's make them find the area of a decagon, using only the perimeter |
| 01:44 - 01:47 | Throw in some stage 5 geometry |
| 01:47 - 01:49 | Base angles of isosceles triangles |
| 01:50 - 01:53 | They might have seen it, maybe |
| 01:54 - 01:56 | If they did 5.3! |
| 01:56 - 01:58 | If they did 5.3! |
| 01:58 - 02:02 | So it becomes a trigonometry problem |
| 02:05 - 02:07 | And then an area of a triangle problem |
| 02:10 - 02:11 | And then.. |
| 02:11 - 02:13 | They better not forget to multiply it by ten |
| 02:15 - 02:17 | They better not forget to multiply it by ten |
| 02:17 - 02:20 | Back to that series question |
| 02:21 - 02:28 | Let's use some notation they might not have seen |
| 02:29 - 02:30 | But Advanced have! |
| 02:30 - 02:32 | If they weren't having a bad day |
| 02:36 - 02:39 | They are now! |
| 02:40 - 02:42 | |
| 02:50 - 02:55 | I should feel bad, but I don't. |
| 02:56 - 02:58 | But what about the standard 2 content? |
| 02:58 - 03:04 | One of the networks questions only requires you to add 10 to a previous answer. |
| 03:04 - 03:09 | One of the networks questions only requires you to add 10 to a previous answer. |
| 03:09 - 03:11 | By that time they will be wondering if there's more to it |
| 03:16 - 03:20 | But there's not! |
| 03:23 - 03:26 | Teachers will curse us! |
| 03:31 - 03:36 | It'll make the English exam boat picture look like NAPLAN |
