Helping Ladybug Hide with Arrows and Angles
http://illuminations.nctm.org/LessonDetail.aspx?ID=L70
A lesson plan for grades K–2 Mathematics and Science
In this lesson, one of a seven-part unit from Illuminations titled “Going Places: Measuring and Mapping,” students use a Java applet to hide a ladybug under a leaf. This requires experimentation, planning, and understanding of spatial relationships and visual memory.
North Carolina Curriculum Alignment
Mathematics (2004)
Grade 1
- Goal 2: Measurement - The learner will use non-standard units of measure and tell time.
- Objective 2.01: For given objects:
- Select an attribute (length, capacity, mass) to measure (use non-standard units).
- Develop strategies to estimate size.
- Compare, using appropriate language, with respect to the attribute selected.
- Objective 2.01: For given objects:
- Goal 3: Geometry - The learner will identify, describe, draw, and build basic geometric figures.
- Objective 3.04: Solve problems involving spatial visualization.
Grade 2
- Goal 2: Measurement - The learner will recognize and use standard units of metric and customary measurement.
- Objective 2.01: Estimate and measure using appropriate units.
- Length (meters, centimeters, feet, inches, yards).
- Temperature (Fahrenheit).
- Objective 2.01: Estimate and measure using appropriate units.
Kindergarten
- Goal 2: Measurement - The learner will explore concepts of measurement.
- Objective 2.01: Compare attributes of two objects using appropriate vocabulary (color, weight, height, width, length, texture).
- Goal 3: Geometry - The learner will explore the concepts of geometry.
- Objective 3.03: Model and use directional and positional vocabulary.
Science (2005)
Grade 1
- Goal 4: The learner will make observations and conduct investigations to build an understanding of balance, motion and weighing of objects.
- Objective 4.01: Describe different ways in which objects can be moved.
Kindergarten
- Goal 4: The learner will use appropriate tools and measurements to increase their ability to describe their world.
- Objective 4.03: Use nonstandard units of measure to describe and compare objects.
- Objective 4.04: Demonstrate the use of standard units of measure and compare with nonstandard units of measure. (Teacher demonstration)
- Objective 4.05: Demonstrate that standard units of measure produce more consistent results than nonstandard units, allowing information to be shared.(Teacher demonstration)
