Sample questions:

Bar diagrams: for a given word problem, draw a bar diagram and a math mountain. Label the bar diagram as well as putting numbers in appropriately. For missing-total problems, write an addition number sentence to find the solution. For missing part problems write subtraction number sentence and missing number addition equation.
