ROCK FALL game to practice
'Biggest number: 50 - 100' for 1st grade

1st grade : Comparing numbers :
Choose the biggest number from 50 to 100

In this topic you are asked to look at a group of numbers and decide which number is the biggest. There are 6 numbers in each group, and each number is between 50 and 100. In the first question, you have the following group of numbers :

66, 71, 79, 86, 77, 69

Start by looking at the first digit of each number - they are 6, 7, 7, 8, 7 and 6. So, if numbers have the same number of digits, then the number with the biggest first digit is the biggest number. We can see that we have a number with an 8 as the first digit, the 86, and the other numbers have smaller first digits so that has to be the biggest number in the group. So in this group the biggest number has to be :

Biggest number = 86


In another question from the topic you are asked to find the biggest number from the following group of numbers :

99, 56, 80, 60, 96, 77

So we use the same technique as last time and look at the first digit of each number in that list. You will see that one of them is a 5, and the others are all bigger numbers, so that 56 cannot be the biggest number.

There are two numbers in the list that start with a 9, so compare their second digit. They are 9 and 6. We know that 9 is bigger than 6 so the biggest number in the list has to be :

Biggest number = 99

With our Rock fall math game you will be practicing the topic "Biggest number: 50 - 100" from 1st grade / Comparing numbers / Biggest and smallest. The math in this game consists of 16 questions that ask you to choose the biggest of a group of numbers between 50 & 100.

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.
