  • Victorian Teachers

    Firstly, we are thinking of you trying to successfully modify teaching and learning in this second 'school from home' event. We hope there is something you can find in this newsletter, or across the breadth of our site that will support you. We're always up for a chat if you would like to.

    Secondly, the department is rolling out new email addresses. If you want to keep receiving these messages you will need to let us know your new address. Just drop a line to doug@blackdouglas.com.au

  • New Maths At Home Activities

    Two new Maths At Home (MAH) activities added through July. They are:

    • Bob's Buttons (Years 4 - 8)
      A video introduces this activity through a game using pretend people in a pretend school ground. The presenter models how the learners can play the game for themselves, then invites them to dig into the investigation to find the question Bob asked that turned it into an amazing investigation. The activity includes hands-on mathematics related to multiplication, free sample software from Maths300 and other learning materials from that site. Learners are working like a mathematician throughout. The early part of the activity would interest many Year 2 students. The deepest question would challenge university students. There is something for every learner in between.
    • Counting Frames (Years K - 2)
      This activity is written for parents who want to develop and extend their learner's ability to count - not just by ones, but twos, fives and any other group. Printable counting frames are provided and you and your learners find the objects to count. Explanation and example in the notes set the scene and provide questions, and a balance of flexibility and structure, to guide you into many short, regular adventures together through the expanding world of a confident counter.
    MAH activities are written on the assumption that students are working at home with a parent around, so are easily spliced into the materials you are sending home, or, if are working face to face at school, used as your lesson plan. They are rich with content and teaching craft.

    For the home environment, the 'voice' of the lesson directly addresses parents for early years activities; in middle years it assumes there is a parent or other learning support person around; and for more experienced learners the 'voice' encourages independent learning and working virtually with mates.

    Every activity has a Gallery section at the end. Think of it as a maths display board in the corridor, that is available for the whole world to see.

    Every activity also involves the deliberate use of maths journals and a self-assessment section. This section sometimes expects students to evaluate themselves against the Working Mathematically process; sometimes to evaluate the content they have learnt and how they feel about it; and sometimes both.

    See Link List below for the web address of Maths At Home, or visit Mathematics Centre (which you probably have bookmarked) and take the link in the banner at the top of the page.

  • New Cube Tube Video

    The video Introducing Bob's Buttons, produced to stimulate the Maths At Home activity, is available through our Cube Tube channel. Of course it leads you back to that activity, but it can also be used independently of MAH in your own classroom however you wish.

    In addition we have redesigned the Cube Tube library index a little to make it easier to find support information for each video. (See Link List below.)

  • Get to Know a Cameo

    Task 77, Tricube Constructions A
    Tricubes are an extremely motivating way to enter the world of 3D space to explore representing objects in various views such as plan and isometric views. Students are shown a looking down view of a 'building' they know is made from all four Tricubes. From this they are asked to construct the 'buildings' (there may be more than one way) and draw them isometrically. This link between the actual 3D object and its 2D isometric drawing is never strong enough if learning in this area of the curriculum comes exclusively from books.
    For example, what are we looking at here?

    A hexagon with interesting diagonals, or a perfect isometric drawing of a transparent cube showing the foreground and background edges?

    In the cameo you will discover that this task appears in Picture Puzzles Shape & Space A menu and as a Maths At Home activity. (See Link List below for both.) You will also discover that you can involve the students in making a class set of Tricubes.
    In the eTask Package this task is in the 'easy to make' set because apart from the task card, you only need four Tricubes, and these are easy to make from 2cm click together cubes which are available in most schools.

    Task 201, Rectangle Fractions
    This practical, visual model has a proven record for supporting far more learners to be able to explore the concept of fractions, equivalent fractions and addition and subtraction of fractions. Skill development grows in parallel with a visual image that really can lead to 'doing them in your head". In the end all it comes down to is imagining the dimensions of a rectangle that could represent both the addends in the fraction question.

    The story shell of the task card is one student explaining to another how she does fraction sums. The challenge is to understand a peer's explanation, rather than that from a text book or a whiteboard, and then apply it to a related challenge.

    The cameo provides clear explanations for teachers, excellent support for a whole class lesson and several references which support the development of a unit of fraction work.

    In the eTask Package this task is in the 'easy' set because the foam plugs in the photo are not commonly available so the task has been rewritten to use a grid that is provided and 2cm blocks, which are common in schools.

Keep smiling,
Doug.
