To Count? Or, not to count? That is the question. Can you look at a carton of eggs and tell how many are left just by looking? Can you determine the amount of people at a table without walking around and tapping each of them on the top of the head? If you said yes to any of these questions then you, my friend, are a SUBITIZER!Su-bi-tize (verb) To perceive (know), at a glance, the number of items quickly presented. Welcome to The Subitize Tree! This is the newest app from TeacherTipster.com! The object of the game is simple. Owl, frog, snail and many more of the forest animals have gotten trapped inside the Subitize Tree. You must perfect your subitizing skills in order to save our animal friends. Save all ten animals to beat the game and become a master subitizer!Getting StartedChoose a difficulty level (easy, medium or hard). This will determine how quickly the doors open and close on the Subitize Tree.Choose what object type you would like to play with. You may choose from playing cards, dominoes, symmetrical arrays, dice, ten frames, rekenreks, hands, random arrays and colored counters.You can also choose random if youd like the game to randomly present items from all of the object types.Touch PLAY.How to PlayTouch the green subitize button and focus your attention on the doors.These doors will open, temporarily revealing a group of items, before slamming shut again.It is your job to subitize the objects while the doors are open! Now, you must decide how many objects you think are behind the door.Touch the number button (1-10) to make your final choice.The doors will re-open and reveal whether your choice was right or wrong.If you were correct you will activate one of the four lights found on top of the subitize box. When four lights are activated, an animal will be set free!Once an animal is released, its matching star will be activated as well.Set all of our animal friends free to beat the game!NotesYou can open the menu at any time to adjust your game play settings (difficulty or object choice).There is no penalty for choosing a wrong answer. You simply wont receive points for that answer.You can isolate the objects in the menu if you want to practice on one particular object type.
