Description: There are 28 cards in the deck relating to the addition of 3 single-digit or one-digit numbers between 11 - 20. Students can add up the numbers mentally or move the finger along the number line to work out each answer. They then type their answer in the space provided to complete the addition equation and click on ‘Submit’. A bell will ring if the answer is correct, and the game will automatically move onto the next card. If an answer is incorrect, a ‘whoops’ is heard, and the answer can be entered again. Hint: If he/she know their number facts to 10, then they can work out the 3-digit equations quickly by adding up to numbers that add up to 10 and count on the last digit. However, some learners may prefer to use the number line to add up the 3 digits.
