Decimal Place Value: Tenths and Hundredths
Students will explore the place value system to include decimals, understanding tenths and hundredths.
Key Questions
- Differentiate the value of a digit in the tenths place versus the hundreds place.
- Construct a model to represent a decimal number like 0.45.
- Justify why understanding decimal place value is crucial for working with money.
NCCA Curriculum Specifications
About This Topic
Proportion and portraiture move students toward a more technical understanding of the human face, using mathematical relationships to guide their drawing. At 5th Class level, students begin to notice that eyes are generally halfway down the head, a discovery that often surprises them. This topic uses shading to transform flat shapes into three-dimensional forms, meeting NCCA standards for developing observational skills and exploring the element of 'form.'
Beyond the art room, this topic connects to History through the study of famous figures and to SPHE by exploring self-identity and how we perceive others. It encourages a deeper 'looking and responding' process where students analyze how light creates depth. Students grasp this concept faster through structured discussion and peer explanation of where shadows naturally fall on the face.
Active Learning Ideas
Inquiry Circle: The Face Map
30
Think-Pair-Share: The Mood of Light
Show two portraits of the same person with different lighting. Students think about how the shadows change the person's 'story,' discuss with a partner, and share with the class how shading creates emotion.
Stations Rotation: Shading Techniques
Set up stations for hatching, cross-hatching, and blending with tortillons. Students spend 10 minutes at each station applying that specific technique to a basic sphere to understand how to create the illusion of a curved cheek or forehead.
Watch Out for These Misconceptions
Common MisconceptionThe eyes are at the very top of the head.
What to Teach Instead
This is a classic developmental stage in drawing. Using a 'blind contour' exercise or physical measurements of a partner's face helps students realize there is a significant amount of space for the forehead and hair above the eye line.
Common MisconceptionShading is just 'coloring in' with a darker pencil.
What to Teach Instead
Students often apply uniform pressure. Using a 'value scale' activity where they must create five distinct shades of grey helps them see shading as a way to define 3D structure and light direction.
