Calculating Percentages of Amounts
Students will calculate percentages of whole numbers and apply this to real-world problems.
Key Questions
- Analyze how a 10 percent increase followed by a 10 percent decrease affects the original amount.
- Design a scenario where calculating a percentage of an amount is necessary.
- Justify the steps involved in finding 25% of a given number.

About This Topic
Clay relief and texture involve creating 'pictures' in 3D by adding to or carving into a flat slab of clay. For 5th Class, this is an excellent way to bridge the gap between 2D drawing and 3D sculpture. Students explore 'additive' (adding clay) and 'subtractive' (carving away) methods to create depth and narrative. This meets NCCA Clay standards by developing skills in manipulating the medium and using tools to create tactile surfaces.
This topic connects to History through the study of ancient stone carvings (like those at Newgrange) and to English through visual storytelling. Students learn how light and shadow change when a surface is physically textured. This concept is best understood through tactile exploration. This topic comes alive when students can physically model the patterns of a story in clay and see how the 'narrative' changes as they add more layers of depth.
Active Learning Ideas
Stations Rotation: The Texture Hunt
Set up stations with different 'found' texturing tools (combs, shells, burlap, screws). Students spend 5 minutes at each station on a practice slab, seeing which tool creates the best 'fur,' 'scales,' or 'bricks.'
Peer Teaching: The 'Slip and Score' Method
In pairs, students practice joining two pieces of clay. One student acts as the 'inspector' to ensure the other has 'scored' (scratched) the surface and used 'slip' (clay glue) correctly so the pieces don't fall off when dry.
Gallery Walk: Shadow Analysis
Once the relief works are finished, turn off the main lights and use a single torch to light the works from the side. Students walk around and discuss which carvings create the most dramatic shadows and why.
Watch Out for These Misconceptions
Common MisconceptionYou can just press two pieces of clay together and they will stay.
What to Teach Instead
Students often skip the 'slip and score' step. Showing them a 'before and after' of a piece that fell off in the kiln surfaces the need for proper joining techniques much faster than just telling them.
Common MisconceptionRelief is just a drawing on clay.
What to Teach Instead
Students often just scratch thin lines. Encouraging them to add 'blobs' of clay for high points and carve deep 'valleys' for low points helps them understand that relief is about physical levels of depth.
