pkrp-about

This activity uses the Tinkercad online design platform to program a three-dimensional scale model of the Matariki cluster of stars, ngā whetū e iwa o te kāhui o Matariki.

Learners will first work with real astronomical data to calculate coordinates for plotting the nine stars of Matariki in three dimensions. They will then use Tinkercad Codeblocks to program a 3D model of the cluster to toggle and explore from every angle!

Dive in to link mathematics, coding, and 3D digital design with the Māori New Year celebration of te putanga o Matariki, the rise of Matariki! Mānawatia a Matariki!

pkrp-diff

  • Simplify the project by preparing the data and getting the maths out of the way, especially for younger learners, so ākonga need only focus on programming and digital design.

  • Make the project more challenging by removing the given astronomical data and guiding ākonga to use digital resources to research the data for themselves.

  • Let ākonga play with colour, shape or other design parameters to help make their celestial model unique.

pkrp-ext

  • Prompt learners to add the star Puanga (Rigel) to their model. You may provide the astronomical data or challenge them to find it on their own.

  • Challenge learners to use a spreadsheet program to organise and calculate their data.

  • Use ‘Message’ Mark Up blocks to include information about each star of Matariki.

  • Prompt learners to research other stars, clusters or constellations and apply the process to add more stars to their 3D model.

pkrp-notes

  • Device Preparation as a pre-lesson task.

  • Group Assignments and logistics, including student collaboration and content focus.

To help make sure device use is safe, supervised, and purposeful throughout. ScratchJr is a closed, tablet-based application with no internet browsing, public sharing, or account requirements in its standard form, making it a lower-risk digital tool. However, here are some things to keep in mind:

  • Make sure the ScratchJr app is up to date.

  • Consider turning off internet access during the activity, as ScratchJr does not require internet access once installed.

  • Remind ākonga to handle tablets with care and to consider what is appropriate language or other contents to include in their project during programming.

  • For younger learners, particularly Y0-2, make sure all tablet use is directly supervised and that the focus is be on guided interaction rather than independent device navigation.

>>> y0-3 | Y0-3, or First Experience with ScratchJr | 1+ Lessons (Directed)

  • Lesson 1 — Introduction & Modelling

    • Introduce te kāhui o Matariki, share the names of the nine stars, and display them visually for reference

    • Kaiako opens ScratchJr and introduces the interface, the stage, sprites, and block palette, etc.

    • Kaiako models adding a star sprite and attaching a tap-trigger block sequence

    • As a class, attach grow and shrink blocks, repeat to create a twinkling loop, and add the star’s name

    • Run the program together, tapping the green flag and watch the stars twinkle

    • Where time allows, ākonga attempt to replicate the animation on their own tablet with kaiako support

  • Lesson 2 — Programming & Sharing

    • Review briefly the ScratchJr interface and stars of Matariki

    • Ākonga complete their own programs, with support, based on the modelling from the previous lesson

    • Run finished programs, sharing and together as a class

      • Kaiako scaffolds testing; does tapping the star result in the right action?

      • Kaiako supports ākonga to debug any issues by thinking critically through problematic outcomes, potential causes, then exploring, applying, and double checking solutions

    • Celebrate the finished programs and twinkling stars; discuss what ākonga learned

>>> y4-6 | Y4-6+ | 1+ Lessons (Guided to Independent)

  • Lesson 1 — Introduction & Programming

    • Brief introduction to te kāhui o Matariki, including the names and significance of the nine stars

    • Kaiako introduces and models the Scratch Jr interface briefly, then ākonga set up their own programs

    • Ākonga test each part of their program; does each trigger result in the right action?

    • Ākonga debug any issues by thinking through the problem and exploring solutions, with support

    • As time allows, encourage groups to share their finished interactive maps, celebrate success, discuss debugging experiences and what ākonga learned, and review the significance of each star

  • Lesson 2 — Extension & Sharing

    • Review briefly the ScratchJr interface and stars of Matariki

    • Ākonga have time to program

      • Unfinished groups complete their programs

      • Capable groups challenge themselves to extend the activity, like expanding their animation to include all nine stars of Matariki, or including sound recording elements from the related Interactive Star Map activity

    • Share finished programs, celebrate success, reflect on what was challenging about the programming, and what was learned about the stars of Matariki>
