This grade-one worksheet by ArgoPrep is all about fractions and reasoning skills. The worksheet continues on with fractions, however this time, students will show the work that led them to their answers and explain the reasoning behind them. This worksheet will challenge students' understanding of fractions and really show what they know when they work to justify the answer they gave. When students can explain the fractions to another person, they show they understand it themselves. This worksheet will allow them to do just that.
