Tips for parents

• Keep counters, blocks or fingers nearby. Young children learn numbers best when they can touch them.
• Do one sheet, check it with the answer key, then redo only the missed problems the next day.
• Turn one problem into a real life question, using snacks, coins or toys around the house.
