Use keyboard arrow keys or tap your tablet/mobile to control the frog and catch the flies. Avoid the birds! Answer the math questions to win additional points.
Scoring is based on speed, flies caught and the number of correct answers.
Kindergarten / Subtraction / Subtracting numbers / Subtraction: bridge through 10
In this topic we are going to look at taking away (subtracting) a single digit number like 4 or 7 from a double digit number like 12 or 15 (this is sometimes called 'bridge through 10' because you are counting down from double digits to single digits through the number 10). This is a little bit harder than subtracting single digit numbers but not much harder. So, how can we work out the answer to the following sum :
12 - 7
We know we can subtract numbers by counting down from the first (bigger) number by the same number of steps as the second (smaller) number. So to subtact 6 - 3, we start with 6 and count down three places to 5 then 4 then 3, and 3 is the answer.
When we are subtracting from a double digit number, we do the same thing. So, for 12 - 7, we are going to start with 12 and count down seven places - so, 11, 10, 9, 8, 7, 6, 5. So we can say :
12 - 7 = 5
If you find counting down hard, a different way to work out the sum is to start with the smaller number and count up to the bigger number, and the number of steps you take will be the answer. So if we have the sum 9 - 5, we can count up from 5: to 6, then 7, then 8, then 9. So that was 4 steps and the answer is 4. For 12 - 7, we would start at 7 then :
The number of steps from 7 up to 12, which is the answer, is 5
Another question from the topic is :
17 - 8
So let's use our counting up method. We start at 8, plus 1 to 9, plus 1 to 10, plus 1 to 11, plus 1 to 12, plus 1 to 13, plus 1 to 14, plus 1 to 15, plus 1 to 16, plus 1 to 17. How many steps was that? It was 9 steps so we can say :
17 - 8 = 9
With our The frog flies math game you will be practicing the topic "Subtraction: bridge through 10" from Kindergarten / Subtraction / Subtracting numbers. The math in this game consists of 16 questions that ask you to subtract a single-digit number from a double-digit number by counting down through 10.
Learn or revise math with our fun interactive game THE FROG FLIES! You are a happy hungry frog in the middle of the jungle in the middle of the night. Catch the flies for your supper (and practice math just for fun).
You can play the game on tablet/mobile or desktop computer. On handheld devices you move the frog by tapping where you want it to move to. On a computer, use the arrow keys on your keyboard to move.
Sometimes a big bird swoops through the forest catching unwary amphibians so stay alert and get out of the way of its beak!
Scoring is based on flies caught, questions answered and number of deaths by bird. Your final score is your total points minus your time in seconds.
