Students in second grade usually can count money, so the next step is teaching them to count back change from a given amount. An example of this is counting back change when someone pays 75 cents for something that cost 62 cents. The Fun Brain website has a game that requires students to make change. Students can make change using amounts up to $1, $5 or $100. Super brain is the highest level. This level uses all denominations of currency. Students can choose a currency from five different countries by clicking on their country's flag and then begin playing.
The Mr. Nussbuam website has a place value game students can play by identifying the place value of a number. The pirate-themed game has five pirates standing on a platform that has a three-digit number on it. Students play by clicking on the pirate that has a given number in the correct place value. For example, the game may request students to click on the pirate that has "4" in the tens place. When they answer correctly, the pirate falls down, and another problem appears. If students get three answers wrong, the game ends, and they'll need to start a new session. Students have two minutes for each session.
Fractions are also part of the second-grade curriculum, and the PBS Kids website has a game students can play to match fractions. The object of the game is to match the correct numerical fraction with the correct picture. For example, students would match the fraction 1/2 to the picture that is half shaded. When the game begins, students match four numerical fractions with four pictures of fractions. As the game progresses, the number of fractions students have to match increases each time a new session begins.
Many second-grade students know how to add, but some may need extra practice to add quickly. Instead of playing games with flashcards or completing worksheets, the Fun School website has a game students can play to increase their math fluency. This carnival-themed game shows students an equation, and then students have to quickly pop the balloon that has the correct answer. The game begins with single-digit addition and quickly progresses to two-digit addition. Students need to get at least five answers correct in one minute to move to the next round. As students move from one round to the other, the problems get harder. If students get three problems incorrect, the session ends, and they must begin a new round.
