Classifying 2D Shapes: Polygons
Students will classify polygons based on their number of sides, angles, and regularity.
Key Questions
- Differentiate what defines a regular polygon compared to an irregular one.
- Construct a Venn diagram to compare properties of different quadrilaterals.
- Justify why a square is always a rectangle, but a rectangle is not always a square.

About This Topic
Linocut and relief printing introduce 5th Class students to the concept of 'multiples' and the unique challenge of thinking in reverse. Students learn to carve a design into a surface, ink it, and transfer the image to paper. This aligns with NCCA Print standards, focusing on the development of technical skills and the understanding of positive and negative space.
This topic connects to History through the study of the printing press and the spread of information. It also builds fine motor skills and patience. Students must plan their design carefully, knowing that whatever they carve away will remain the color of the paper. This concept is best understood through collaborative investigation of how different 'marks' print. This topic comes alive when students can physically model the patterns of their design and see the 'magic' of the first reveal as they peel the paper back.
Active Learning Ideas
Inquiry Circle: The 'Inky' Experiment
In groups, students test how much ink is 'just right.' They create three prints: one with too little ink, one with too much, and one 'perfect' one. They label them and create a guide for the rest of the class to follow.
Think-Pair-Share: The Mirror Image
Students write their name on a small piece of paper and look at it in a mirror. They pair up to discuss why writing or asymmetrical shapes are 'tricky' in printmaking and how they can plan their carving to fix this.
Gallery Walk: Edition Comparison
Students hang a 'series' of three prints of the same design. The class walks around to find the most consistent 'edition,' discussing why some prints in a series look different from others (e.g., pressure, ink levels).
Watch Out for These Misconceptions
Common MisconceptionYou carve the lines you want to see.
What to Teach Instead
Students often forget that relief printing is 'backwards.' Carving a line makes a white space, not a dark one. Using a 'black and white' marker sketch first helps them visualize that they are 'carving the light' and leaving the 'dark' behind.
Common MisconceptionThe more ink, the better the print.
What to Teach Instead
Students often flood the block with ink, which fills in the fine details. The 'Inky Experiment' helps them see that a thin, 'velvety' layer of ink produces the clearest image.

Planning templates for Mathematical Mastery: Exploring Patterns and Logic
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
unit plannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
rubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.
