Learning Objectives
Enduring UnderstandingLength can be represented
by different symbols and is communicated using
common standards.Objectives1. Students will be
able to measure using non-standard units
(blocks).2. Students will be able to explain why
measuring with two different nonstandard units (2
sizes of blocks) can be confusing.
3
Educational Context Alignment
Corresponding NCTM K-2 Standard Understand
measurable attributes of objects and the units,
systems, and processes of measurement understand
how to measure using nonstandard and standard
units. Corresponding California First Grade
Standard Measurement and Geometry 1.0 -
Students use direct comparison and nonstandard
units to describe the measurement of objects.

Summary of School

• School (Don Callejon Elementary)
• 1st graders
• Previous knowledge
• Why measurement?
• Content to be covered

Physical/Social Settings

• Physical
• Computer Lab in school
• One PC per student
• Social
• Lesson structure
• Student demographics
• Animals!

6
Pedagogical Approach

• Guided Exploration
• Explore concept using a storybook with audio
• Learner gets to make decision (learner control)
• Questions at appropriate stage
• Builds on previous knowledge (counting)
• Clear focus on concept and thinking

7
Pedagogical Approach

• Modeling
• Make thinking (Owls explanation) explicit to
  support development of learners reasoning skills

8
Pedagogical Approach

• Reflection
• Worksheet after game
• Transfer of concept
• Sharing (in groups of four) on learners thinking

9
Development

• Initial classroom observation
• Interview with teacher
• Prototyping
• Feedback from class
• Feedback from teacher

10
Curriculum

• Pre-Activities
• Applet Instructions and Assessment
• Post-Activity

Next Steps

• More explicit directions on how to match ruler or
  blocks with the bottom of the feet
• Improve feedback when child incorrectly
  identifies how tall/long an animal is.
• Have instructional audio automatically replay if
  child has not done anything for a length of time.

19
Next Steps

• Emphasize that the child needs to stack ALL of
  the blocks, and include this in the instructional
  audio that replays
• Add extra fun things to find on the screen if
  the child plays through the game a second time.
• Include several end screens where child can
  measure with a ruler with feedback mechanism

20
Next Steps

• Show an animation of how to count up on a ruler
• Add in extra animals to measure at the end.
• Include initial explicit directions on how to
  move to the next screen.
• Do in Flash.
