D691 is the mathematics content course in WGU's Bachelor of Arts in Elementary Education, listed at 3 competency units. WGU describes it as covering the concepts suitable for young learners: numbers, operations and algebraic thinking, geometry, measurement, data, statistics and probability.
Future teachers sometimes expect it to be easy because the maths is elementary. The challenge is that you must explain why methods work, not only get answers, and relate the content to standards and classroom resources. A correct answer without a clear explanation rarely satisfies a competency.

What D691 Covers
| Competency (WGU wording, summarized) | What it means in practice |
|---|---|
| Analyses elementary content standards and resources in mathematics | Reading standards closely and judging resources against them |
| Explains major concepts in data, statistics and probability | Representing data, central tendency, chance |
| Explains major concepts in geometry and measurement | Shapes, perimeter, area, units |
| Explains major concepts in numbers, operations and algebraic thinking | Place value, the four operations, fractions, patterns |
Key Concepts Explained
Explaining, Not Just Calculating
Example, fractions: Why does 2/3 equal 4/6? Draw a bar split into three equal parts with two shaded. Cut each part in half: now six parts, four shaded. The amount shaded has not changed; it has been named with smaller pieces.
Perimeter and Area
Example: A 3 by 5 rectangle has perimeter 3 + 5 + 3 + 5 = 16 units, but area 3 x 5 = 15 square units. Children often mix the two because both use the same side lengths. Explain that perimeter measures distance around, area measures covering.
Data and Probability
Example: For the numbers 2, 4, 4 and 6, the mean is 16 / 4 = 4, the median is 4 and the mode is 4. If a bag holds 3 red marbles among 8, the chance of drawing red is 3/8.
Typical Assignments and How to Approach Them
| Work type | What it tests | How to approach it |
|---|---|---|
| Standards and resource analysis | Alignment | Quote the standard, then show where the resource meets or misses it |
| Concept explanations | Understanding | Use a model or drawing plus a sentence of reasoning |
| Problem solving with justification | Accuracy and reasoning | Show each step and say why it is valid |
A Competency-by-Competency Study Approach
- Numbers and operations. Practice place value, regrouping and fractions with drawings.
- Geometry and measurement. Sort shapes by properties and convert units.
- Data and probability. Build tables and graphs, then describe what they show.
- Standards. Pick one standard per domain and write what a child must understand.
Where Students Get Stuck
- Procedure without meaning. Be ready to justify every step.
- Fraction reasoning. Use number lines and area models.
- Vocabulary. Terms like "partition" and "decompose" have exact meanings.
- Standards language. Break each into the idea and the evidence of learning.
Planning Table
| Domain | Core idea | Practice |
|---|---|---|
| Numbers and algebra | Place value, operations, patterns | Explain with models |
| Geometry, measurement | Properties, area, units | Draw and measure |
| Data, probability | Represent and interpret | Build tables and graphs |
How to Analyze a Standard
Standards are written compactly, so unpack them. A useful routine has four steps.
- Underline the verbs. They tell you what children must do: compare, represent, explain.
- Circle the content. Which numbers, shapes or data are involved?
- Write the idea in plain words. What must a child understand, not only do?
- Describe evidence. What would a child say or draw to show mastery?
Example: A standard asking pupils to compare two fractions with the same numerator becomes: "Pupils understand that when the pieces are the same in number, smaller pieces make a smaller fraction." Evidence: a pupil draws two bars and explains that 2/5 is more than 2/8 because fifths are bigger than eighths.
Judging a Resource
When asked to evaluate a resource, check alignment (does it teach the standard's idea?), representation (does it use models?), language (is it clear?) and accessibility (can all learners use it?). A resource that offers only procedures with no models is a weak match for a standard about understanding.
Study Tips for D691
- Say each explanation aloud as though to a nine-year-old.
- Draw a model before using a formula.
- Keep a vocabulary list with a picture for each term.
