In grades 3-5, students begin to use words, letters, numbers, symbols, or pictographs to represent information in another form (similar to using variables in math to represent unknown numbers), including using group names to represent any member of that group (such as "triangle" to represent "any 3-sided figure).
They continue to build their ability to break down large problems into smaller sub-problems, chunking common sets of steps that they can refer to all at once by naming it.
They use graphs to represent larger data sets, and use these visualizations to make conjectures about the phenomenon the data represents (perhaps comparing two different data elements on the same chart).
Students explore population cycles of organisms within a habitat.
Students encounter input-output machine imagery to see steps in some interesting algorithms that involve fractions.
Students learn how force and motion can be transferred through chain reactions.
Students explore electrical circuits to demonstrate how energy can be transferred from place to place.
Students encounter input-output machine imagery to see steps in some interesting algorithms that involve fractions.
Students use an online environment to read a story about how plants grow under different conditions. They reflect on their understanding through writing and use models and test variables.
