                  Rahul wants to count more blocks in his toy shop. Let us see how he counts more

                  than one hundred blocks.

                                                                                                   Be Aware
                                                                                           There is a 0 in the tens place.
                                                                                           It means there are no tens.

                                                                                  H T O
                          100                    5                     105        1 0 5

                     One hundred               five                     One hundred five
                  This is a collection of 105 blocks. The number name of 105 is one hundred five.

                  This way we can build numbers from 101 to 109 by keeping 1 in the hundreds place,

                  0 in the tens place and changing numbers from 1 to 9 in the ones place.

                                                                                                   Be Aware
                                                                                           There is a 0 in the ones place.
                                                                                           It means there are no ones.

                                                                                  H T O
                          100                   20                     120        1 2 0

                     One hundred              twenty                  One hundred twenty
                  This is a collection of 120 blocks. The number name of 120 is one hundred twenty.

                                                                                                H T O

                          100                   40                7                  147        1 4 7
                     One hundred               forty            seven               One hundred forty-seven
                  This is a set of 147 blocks and the number name of 147 is one hundred forty-seven.
