ROCK FALL game to practice
'Sort numbers to 100 large to small' for 1st grade

1st grade : Ordering numbers :
Order numbers up to 100 from largest to smallest

In this topic you are asked to look at a mixed up list of numbers up to 100 and sort them so that the first number is the biggest, the next number is the second biggest and so on. There are 4 numbers in each list, and the numbers can be as big as 100 and as small as 1. In the first question, you have the list :

87, 78, 99, 34

Start by looking at the first digit of each number. They are 8, 7, 9 and 3. A two digit number that starts with a 9 is bigger than a two digit number that starts with an 8 or a 7 or a 3 so that number (the 99) has to be the biggest number in that list.

Look at the remaining three numbers - we can do the same trick of comparing their first digits - one of them starts with an 8 but the others start with 7 and 3 so the one starting with an 8 (the 87) must be the next biggest number.

Two numbers left... one of them starts with a 3 but the other one starts with a 7, so the one starting with a 7 (the 78) must be bigger than the one starting with a 3 (the 34). So the sorted list has to be :

99, 87, 78, 34


In a different question from the topic you are asked to sort the following list :

69, 62, 86, 45

So we use the same technique as last time and look for the largest number in that list. Look at the first digit of each number and you will see that one of them is an 8, and the others are smaller numbers, so that 86 has to be the biggest number.

There are two numbers in the list that start with a 6, so compare their second digit. One of them is a 9 and the other is a 2, so the one with the 9 (the 69) is next biggest. The smallest number must be the one that starts with a 4, that is 45. So the sorted list is :

86, 69, 62, 45

With our Rock fall math game you will be practicing the topic "Sort numbers to 100 large to small" from 1st grade / Comparing numbers / Order numbers. The math in this game consists of 16 questions that ask you to pick the correct order for lists of numbers up to 100 from largest to smallest.

Large thumbnail for math game Rock fall

ROCK FALL is based on the road traffic warning sign for falling rocks - a sign that seems a bit less useful than somebody getting up there on that cliff and actually doing something about it... Anyway, the rocks are falling and it is your job to stop them hitting the road below, or at least stopping them hitting the road below too many times and breaking it. Smash the rocks by clicking or tapping on them (not so easy in real life of course) - they will turn into snowflakes and float gently down into nothing.

There are 4 rocks to stop and not much time to do it (if you want to get a good score and get on the leaderboard). This game is fun and fast and requires good reflexes and a good strategy. Plan to break the smaller rocks first if you want a good score because the rocks fall faster as the game progresses. It also helps to decide where on their path you plan to click / tap the rocks.
