Using U.P.S

I wrote this maths problem with,Victoria and Charmaine

      Charmaine,Victoria,Sakina went to the zoo.They saw 7 giraffes,10 lions,24 spider monkeys and 9     elephants. How many animals did they see altogether?

I will use the UPS strategy to work it out.

                 

U-These numbers and word altogether are important in the question.              7,10,24,9 [altogether]

                                         

                                        

P: The word altogether tells me that it will be an addition problem       [altogether means addition]

                          

                                

                                       

                                         

S:I will solve this problem by using place value. 7+10+24+9=50 7+9=16 10+24=34 34+16=50
