In math this week, the children practiced using fractions to name parts of a collection. They learned about “equivalent fractions,” and identified fractions that mean the same fractional part of the whole. With fraction cards, the children worked to find pairs of equivalent fractions. Finally, we specifically found equivalent fractions for ½, including 2/4, 3/6, and 4/8. The children noticed that when the numerator increases in these fractions, the fraction equals MORE than half. When the numerator drops from the halfway mark, the fraction is LESS than half! The children practiced finding equal groups by creating arrays with counters, and were challenged to identify 1/2, 2/3, 3/5 etc. of the group. Our unit on fractions ended this week with our assessment on Friday. We are looking ahead to Unit 9!
Welcome to our 2nd Grade classroom blog! Check in periodically to learn about the fun we are having this year! Take a peek at photos of special events and projects, see what's coming up, and more. Thanks for stopping by!
