Spot the geometric shapes vs Integer Multiplication

Spot the named shape among four spinning wireframes before the clock runs out. Cone, cube, pyramid, torus: each round names one, four turn on the sheet, and one tap decides. HOW IT PLAYS • Four wireframe shapes rotate on a blueprint sheet and the name of one is written above. Tap it. • The time shrinks as your score grows: five seconds at the start, under two seconds past 25. • One miss ends the run. The board stays, the right answer is drawn in red, and Again sits under your thumb. PLAY TOGETHER • Challenge a friend: share your result and they play the exact same sequence of boards, then see whether they beat you. • Live duel over Game Center for two to four players: everyone gets the identical sheet, plays to their own miss, and the highest score wins. Rematch straight from the result card. • Room codes: start a room and pass on its five-character code; everyone who types it joins the duel, no invitation needed. SCORES • Game Center leaderboards for best score and games played. • Best and last score on the menu, a small celebration for a new best. A native rebuild of the 2014 original. English and Romanian.

Integer Multiplication is designed to help students understand the meaning of multiplying positive and negative numbers. The set of integers is closed for multiplication and therefore all products for integers from -10 to +10 can be represented on a -10 x 10 grid. Use the gold sliders on the x and y axes to set the two numbers to be multiplied. Positive products are shown with a black rectangle and negative products are shown in red. Tap the question mark to begin a quiz. The app automatically tracks the number of correct answers. Students are motivated by the sound effects and visually appealing display.
