Last week, our maths focus was solving vertical addition equations.
We improved our addition skills earlier in the year by focussing on a range of mental strategies. Sometimes, vertical addition is a useful method to use, particularly if you are working with larger numbers or decimals.
Earlier in the week, students practised adding two, three and four digit numbers together using the vertical addition strategy. Once students were confident with this addition method, they could begin making a short instructional video to demonstrate their knowledge. This task involved:
1. Choosing an addition problem involving two, three or four digit numbers.
2. Deciding what resources and materials to use to model the problem.
3. Solving the problem aloud using the correct mathematical language.
4. Writing a script and rehearsing with a partner.
5. Filming the video using an iPad.
Here are some of our instructional videos.
This was our first attempt to make instructional videos. We learnt a lot of skills from this experience, including:
- The importance of using the correct mathematical language
- Speaking clearly and loudly
- Using equipment successfully
- Holding the iPad steady while filming.
We plan to make more videos with our iPads to demonstrate other mathematical concepts later in the year.
