She may not be ready for the money part yet. At her age it is not uncommon for a child to get “stuck” after doing well on a section of math. Children in the young school ages are still growing rapidly and sometimes they need a break from some of their schoolwork to allow for maturity. It is important that you move through math at your daughter’s pace. Pushing on when she is not ready, will not help her grasp the concepts and you will both end up frustrated. Because she is so young, it is better to put formal math lessons aside for a few weeks and allow her to mature a bit before continuing lessons. Always teach the child, not the curriculum (or the expectations of others.)
While formal math lessons are on hold, you can still have her practice math in every day situations, such as when setting the table for a meal (“We have 3 forks on the table, but we need 6 forks for the meal. How many more forks do we need?”), folding laundry (You had two pairs of pants and four socks in the laundry. How many articles of clothing did you have altogether?), and playing store (You have 3 oranges that cost 2 cents each. How much do the oranges cost?”)
