- Academic standard
- 1.G.3 Partition circles and rectangles into two and four equal parts; describe the parts using the words halves, fourths, and quarters; and use the phrases half of, fourth of, and quarter of. Describe the whole as two of, or four of, the parts. Understand for partitioning circles and rectangles into two and four equal parts that decomposing into equal parts creates smaller parts.
- Performance measure
- Students will complete a sorting task in which they place picture cards into halves, quarters, and not equal parts, and explain one choice verbally. They will correctly partition at least 3 of 4 shapes into two or four equal parts, accurately use vocabulary, and correctly describe the whole as two halves or four fourths on the exit ticket.
- Learning objective
- The student is expected to partition circles and rectangles into two and four equal parts; describe the parts using the words halves, fourths, and quarters; and use the phrases half of, fourth of, and quarter of. Describe the whole as two of, or four of, the parts. Understand for partitioning circles and rectangles into two and four equal parts that decomposing into equal parts creates smaller parts. They will correctly partition at least 3 of 4 shapes into two or four equal parts, accurately use vocabulary, and correctly describe the whole as two halves or four fourths on the exit ticket.
- Objective statement
- “Today we will split circles and rectangles into equal parts called halves and fourths (quarters), practice saying ‘half of’ and ‘fourth of,’ and show learning by sorting shapes, drawing equal parts, and completing an exit ticket with 3 of 4 shapes correct.”
- Purpose of learning
- “Knowing halves and fourths helps us be precise when we share or measure, like cutting a sandwich in half to share fairly or dividing a pizza into four equal slices. Learning this today builds our fraction skills so we can solve real life problems and be fair when we split things.”
- Connection to prior learning
- “Yesterday we practiced identifying and drawing basic shapes like circles and rectangles, and we talked about what makes parts equal. We also used words like same, equal, and fair. That work helps us today because when we partition shapes, the parts must be equal to be called halves or fourths. We will use the same ideas of equal size as we split shapes and name the parts.”
