The Power of Place Value and Operations · Autumn Term

Comparing and Ordering Integers and Rational Numbers

Students will compare and order integers and rational numbers (including fractions and decimals) using number lines and appropriate symbols.

Key Questions

  1. Justify the placement of positive and negative numbers on a number line.
  2. Compare the values of fractions and decimals by converting them to a common format.
  3. Explain how to order a mixed set of integers, fractions, and decimals from least to greatest.

About This Topic

Monoprinting and Multiples introduces 3rd Class students to the 'magic' of the transfer process. Unlike drawing directly on paper, monoprinting involves creating an image on a smooth surface and then pressing paper onto it to reveal a unique impression. This topic teaches students about the concepts of reversal, ink density, and the unique qualities of printed marks. It aligns with the NCCA Print strand, where the focus is on experimenting with various printmaking techniques and understanding that art can be reproduced.

This topic encourages a sense of play and discovery. Because the final result is often a surprise, it helps students move away from a fear of making mistakes. Students thrive in this topic when they can engage in collaborative investigations, comparing how different amounts of ink or pressure change the final 'pull' of the print.

Active Learning Ideas

Watch Out for These Misconceptions

Common MisconceptionThe print will look exactly like the drawing on the plate.

What to Teach Instead

Students are often surprised by the mirror image. Peer discussion after the first 'pull' helps them realize they need to plan for reversal, especially when using letters or numbers.

Common MisconceptionMore ink always means a better print.

What to Teach Instead

Too much ink often fills in the lines, resulting in a blurry blob. Hands-on 'ink trials' allow students to see that a thin, even layer actually produces the sharpest details.

Frequently Asked Questions

What can I use as a printing plate if I don't have professional equipment?
Laminated card, old plastic folders, or even the surface of a clean desk work perfectly. Gel plates are popular but expensive; a simple piece of Perspex or a smooth baking tray is a great, low-cost alternative for 3rd Class.
How can active learning help students understand printmaking?
Printmaking is inherently a process-based activity. Active learning strategies like 'The Ink Lab' encourage students to act as scientists, testing hypotheses about pressure and ink. This hands-on experimentation helps them master the technical skills of the medium through trial and error rather than just following a set of rigid instructions.
Is monoprinting too messy for a standard classroom?
It can be, but using water-based block printing inks makes cleanup much easier. Setting up a 'printing station' with clear boundaries and a designated 'clean hands' person in each group helps manage the workflow.
How does this topic link to other subjects?
It links to Maths through the concept of symmetry and reflection. It also connects to History when discussing how early books were printed or how Irish artists like Harry Clarke used print and line in their work.
