Jack takes 250 minutes to go to and from school each week. He walks 0.2 of the
time, and rides the bus for the rest of the time. How many minutes does Jack
steps of a solution.
I must determine
the number of minutes Jack spends walking.
0.2 is two tenths. In the model, one tenth is a column of 25,
so two tenths is 50.
Jack walks for 50 min each week.
Use base ten
blocks to model 250 as 10 columns of 25.
