Defining the Fraction: Numerator & Denominator
Understanding the roles of the numerator and denominator in representing parts of a whole.
Key Questions
- Explain why the denominator gets larger as the actual piece of the fraction gets smaller.
- Analyze what it means for a fraction to be equal to one whole.
- Construct a visual model to prove that two different looking fractions represent the same amount.

About This Topic
Relief Printing introduces 3rd Year students to the concept of the 'multiple'. Unlike a drawing, which is a unique object, printing allows an artist to create many copies of the same image. This topic aligns with the NCCA Print strand, where students explore the process of transferring an image from a raised surface to paper. They learn to create printing blocks using materials like foam, cardboard, or even vegetables, discovering how the 'negative space' (the parts they cut away) is just as important as the 'positive space'.
A key challenge in relief printing is 'mirroring', understanding that the final print will be a reversed version of the block. This requires students to think ahead and plan their designs carefully. This topic is highly process-oriented and benefits from station rotations where students can experiment with different inking and pressing techniques. Students grasp this concept faster through structured discussion and peer explanation during the 'proofing' stage.
Active Learning Ideas
Stations Rotation: The Print Lab
Set up stations for different parts of the process: one for 'carving' (using dull pencils on foam), one for 'inking' (using rollers and trays), and one for 'pressing' (using clean rollers or spoons). Students rotate to complete their first edition.
Think-Pair-Share: The Mirror Mystery
Students write their initials on a piece of paper and then try to draw them 'backwards' as they would appear on a printing block. They swap with a partner to check if the reversed letters would print correctly.
Inquiry Circle: Pattern Repeat
In small groups, students use their individual blocks to create a large-scale patterned 'wallpaper'. They must decide on a layout (grid, brick, or random) and work together to keep the spacing and ink levels consistent.
Watch Out for These Misconceptions
Common MisconceptionThe parts I draw on the block will be white on the paper.
What to Teach Instead
Students often get confused between what is 'inked' and what is 'cut'. A quick 'rubbing' with a crayon over their block before inking helps them see exactly which parts will pick up the color.
Common MisconceptionMore ink always makes a better print.
What to Teach Instead
Too much ink fills in the fine details. By doing a 'test print' (ghost print) and comparing it with a partner's, students learn that a thin, even layer of 'tacky' ink produces the clearest results.
