FREE again – Subtracting Sardines, an educational app that helps young kids (preschoolers/kindergarten) understand the concept of subtraction. With the help of a cute little penguin, kids subtract (up to 9) using sardines. This app meets the Common Core Standards for kindergarten. First grade standards are a bit more rigorous and expect students to add & subtract up to 20. There are a lot of good things about this app. The sardines are displayed on a keyboard with domino like keys (number on the left/picture on the right). The child chooses a subtraction problem and the sardines appear at the top of the screen. Here’s how it works: If a child chooses 7 – 2: 7 sardines appear then 2 sardines are taken away. As the child counts the remaining fish, they are encased in ice. Only the bones left behind of the subtracted fish and they disintegrate if touched. The app even allows for subtraction problems with negative answers (red fish joins the left over bones). Children earn gold coins as they work. This nicely done app helps kids with the beginning concepts of subtraction.
Common Core Standards met:
- K.OA.2 – Add and subtract within 10, e.g., by using objects or drawings to represent the problem.
