This five day set of worksheets to guide your lessons is tightly aligned to 4.NF.1 and MP.3. The activities are carefully designed to focus on the denominators of 2, 3, 4, 5, 6, 8, 10, 12, and 100 which are asked for in the standards. The first few days begin with an exploration with equivalent fractions and connections between the work with manipulatives and finding a pattern (MP.7). Students also look at some student work to determine where mistakes might lie. On days three and four students use that they know about equivalent fractions to find missing values. Finally, on day five, they use what they have discovered to prove sets of fractions equivalent. These resources focus exactly where the standards focus!
