This iPad app for 4 – 7 year olds was FREE when I downloaded. It is currently $1.99 but through August 31 the developer is doing a buy one get one free promotion. Happi 123 teaches counting, adding, subtracting, number series, and patterns. The lessons do not have to be done in order so kids can choose what they would like to work on. Each level has practice followed by a puzzle to further reinforce the concept. There is also a combination level where all concepts are mixed and timed. Kids earn badges and disguises for Papi the Tiger as they learn. Several languages are included in the game: English, Swedish, Danish, Norwegian, Italian, German. In the settings, parents can reset the game and disable audio help (which makes the problems more difficult but also less confusing). If the audio help is not disabled, the child has to count the objects at the top of the page in order: top row, left to right followed by bottom row, left to right. Otherwise the counting is not in order and might sound like this: one, two, three, four, five, eight, seven, six. Suggestion for the next update  – make counting the objects (along the top) work like the fingers (along the bottom). The fingers count in order no matter which one is touched first. Nicely done!

Common Core Standards met:

• K.CC.4 – Understand the relationship between numbers and quantities; connect counting to cardinality. When counting objects, say the number names in the standard order, pairing each object with one and only one number name and each number name with one and only one object. Understand that the last number name said tells the number of objects counted. The number of objects is the same regardless of their arrangement or the order in which they were counted.
• K.OA.1 – Represent addition and subtraction with objects, fingers, mental images, drawings, sounds, acting out situations, verbal explanations, expressions, or equations.
