Students calculate an exact square root and estimate approximate square roots by finding the length of the square flower bed of a given area, and give an explanation for their answers.
In this task students build the next two models of a spatial sequential pattern and then use their results to predict subsequent patterns and give general rules for these in words and in equations.
Students compare drawings of a healthy and unhealthy plant and decide which quantitative and/or qualitative data distinguishes them. They draw conclusions from the data. This is a mathematics/science resource.
