This is a great daily activity to be used as morning work or in math centers. Students (or teachers) can choose a number of the day and then are expected to represent the number in multiple ways (base ten blocks, tally marks, expanded form, in words).
They are also asked to show the relationship to other numbers (number line, 1 more, 1 less, 10 more, 10 less, 100 more, double). Student then create addition and subtraction sentences and compare the number to other numbers.
The final space gives students an opportunity to make a connection (ex. "12 is like a dozen eggs, 6 on each side"). This activity can be modified and differentiated for students by using smaller and larger numbers based on their ability level.
