                  Adding Tens with Ones by regrouping

                  1.  2 tens + 12 ones

                       = 2 tens + 10 ones + 2 ones

                       = 2 tens + 1 ten + 2 ones
                       = 3 tens 2 ones                                                =

                  2.  4 tens + 26 ones
                       = 4 tens + 20 ones + 6 ones

                       = 4 tens + 2 tens + 6 ones
                       = 6 tens 6 ones

                                                                               =

                  1.  regroup the following ones into tens and ones.

                       (a) 44 ones = __ tens + __ ones                  (b) 57  ones = __ tens + __ ones
                       (c) 70 ones = __ tens + __ ones                  (d) 81  ones = __ tens + __ one

                  2.  regroup and add the given tens and ones.

                       (a) 5 tens + 16 ones                             (b) 4 tens + 25 ones
                           = 5 tens + __ ones + __ ones                      = 4 tens  + __ ones + __ ones

                           = __ tens + __ ten + __ ones                      = __ tens  + __ tens + __ ones
                           = __ tens + __ ones                               = __ tens  + __ ones

                       (c) 7 tens + 27 ones = __ tens + __ ones
                       (d) 4 tens + 35 ones = __ tens + __ ones

                       (e) 1 ten + 55 ones = __ tens + __ ones

                  Shikha has 23 crayons. She takes 7 crayons from her brother.

                  How many crayons does she have now?

                  To find the total number of crayons, we need to add 23 and 7.

                  We write the numbers one below the other according to their
                  place value and then add them.
