Qualities of a Good Technological Resource

- Depth of the Underlying Mathematics (rich mathematical concepts and structures) Through the Window (NRICH, T Resource page)
- Interactive and engaging Duck: Think Outside the Flock
- Visual (patterns and structures are made visually apparent, uncovers the math) Square It (NRICH, geometry) Remainders
- Facilitates Differentiation: Easy to Learn, Hard to Master (ramp up smoothly); Operates on Multiple Levels (age groups, principles) Thinking Blocks (open-ended tool, visualization), Using Low Threshold High Ceiling Tasks ...
- Accomplishes a goal in a way not possible otherwise Leapfrog (strategy, pattern, smaller problem, count & record, feedback)

**PD: Understanding Practice Standard 6: Attend to Precision** (Explain SMP 6)

- Standards for Mathematical Practice: Commentary and Elaborations for K–5
- K-5 Standards for Mathematical Practice - 6. Attend to Precision (McGraw-Hill)
- Children’s Understanding of Equality (TCM article)
- Carlos and Sarah Present Their Solutions (Teaching Channel)

Classroom: Implementing CCSS Practice Standard 6 (no essay)

- A Maths Dictionary for Kids (Australia, interactive, math language)
- In Order (NRICH, units of measure, judge what level of precision is necessary, solutions)
- Developing Early Number Sense (Virginia, "say it to play it")
- Place Value Number Line (NLVM, zoom in to make more precise)
- Which Symbol? (meaning of symbols, equality, interactive)

Effective practice ...

- reinforces correct answers, not guesses
- removes stress associated with timed tests
- accomplishes several purposes: conceptual understanding, number sense, reasoning, strategic thinking
- and therefore connects them with somewhat meaningful, making them more accessible for problem solving
