Standard: 4.3 - Patterns and Algebra

 

Strand: C - Modeling

 

Cumulative Progress Indicator: 1 -  The student will recognize and describe change in quantities

    ·        Graphs representing change over time (e.g., temperature, height)

 

Grade: 3

 

Sample Activities:

 

·        Students keep a daily record of the temperature both inside and outside the classroom. They graph these temperatures and look at the patterns.

 

·        Students keep a monthly record of their height and record the data collected on a bulletin board. At the end of the school year, they describe what happened over time.

 

·        Students play catch with a ball in the school playground. One person counts out the number of times the ball is thrown, the other counts out the distance that it travels, a third person adds that distance to the total, and a fourth person records the totals. Afterwards they discuss how the total distance changes over time; they recognize that the same amount is added repeatedly.

 

·        Students study the changes in the direction and length of the shadow of a paper groundhog at different times of the day. They relate these observations to the position of the sun (e.g., as the sun gets higher, the shadow gets shorter).

 

·        Students discuss how ice changes to water as it gets hotter. They talk about how it snows in January or February but rains in April or May.

 

·        Students plant seeds and watch them grow. They write about what they see and measure the height of their plants at regular time intervals. They discuss how changes in time result in changes in the height of the plant. They also talk about how other factors might affect the growth of the plant, such as light and water.
