Go for the Gold!
These worksheets can be used to practice or assess the Common Core Standards for addition and subtraction. It's up to you.
Each competition features a different thinking strategy and it comes in three levels. The Bronze Medal level includes the single-digit facts that students should eventually “know from memory”. The Silver Medal level requires them to use mental strategies to add within 20. The Gold Medal level challenges students to use strategies to add within 100.
Kids love the challenge of trying to beat the highest level and “Go for the Gold!”
