Improve your students number sense with a 5 minute daily activity. Using the day number of the school year (from 1 to 180), students practice composing and decomposing numbers. Students learn prime factorization, finding multiples, factors, and fractions of a number. Students learn to identify patterns and understand their significance in mathematics.
"Number Sense and the Days of School" contains many activities to enhance student number sense that can be done at the start of the school year, or during the year as needed.
