# Elementry Problem solving skills Level 5

The Talent academy Elementry problems will prepare the students to exceed the rigors of your core curriculum by our developing and giving higher-order problem-solving skills. The experts at Talenta Academy, main goal is to get the students ready to perform tremendously well and to cross each level of problem-solving. Problem-solving should be an integral part of daily math. The problems are selected carefully and analysed so that experts can predict the mathematical ideas that will underscore students’ problem-solving efforts and in this, we are here to help you and to guide you with all the aspects and ways to solve problems at the quickest possible way. Students should implement problem-solving skills in day-to-day life as this prepares the students for a broader mindset with everyday activities.

Mrs. Jones had some white paint and some green paint, and a bunch of wooden cubes. Her class decided to paint the cubes by making each face either solid white or green. Juan painted his cube with all 6 faces white--Julie painted her cube solid green. Hector painted 4 faces white and 2 faces green. How many cubes could be painted in the fashion, so that each cube is different from the others? Two cubes are alike if one can be turned so that it exactly matches, color for color on each side, the other cube. Answer :10 The sum of my two digits is 13. I am not divisible by 2. list all possible number I could be. Answer :85, 67, 49 Solution : Students might list all the pairs of single digits with a sum of 13. Each such pair of digits make up.2 two-digit numbers. Only the resulting numbers with the odd digit in the units place is not divisible by 2. 8+5=13, giving 85 as a solution (but not 58) 6+7=13, giving 67 as a solution (but not 76) 4+9=13, giving 49 as a solution (but not 94) Help Text : The answer is in the form: 22,43,87

What do you know about metrics? Choose the right option from each that would make sense. 1. The weight of a pineapple: (A) 1 kg (B) 1 g (C) 1 mg 2, The capacity of a can of soda: (D) 35 mL (E) 3.5 mL (F) 350 mL 3. The temperature on a summer day: (G) 30°C (H) 3°C (I) -3°C 4. The distance from New York to Miami: (J) 2200 cm (K) 2200km (L) 2200 mm Answer :1 kg; 350 mL; 30° C; 2200 km Expected Answer : "A,F,G,K" Solution : Students should be encouraged to use “bench mark” metric measurements to estimate reasonable answers. For example, their math book weighs about a kilogram, a mL is about one drop from an eyedropper, a comfortable room temperature is about 30° C, and the distance across the United States is about 5000 km The girl scouts were going on a field trip to the zoo. There are 25 people going. They rented vans and each van has only 7 seat belts. How many vans do they need? Answer :4 Expected Answer : "4" Solution : Students might divide the total number of people going by the number of people that can fit in one van, with one person per seat belt. If so, they should realize that 21 people can go in 3 vans, but an extra van is needed for the remaining 4 people. This is a case in which the answer to a division problem requires rounding the decimal remainder up, rather than to the nearest whole number.

Look at these two page numbers: 131 and 132 a. Is their sum an even number, or an odd number.________ (Choose odd or even) b. Is their product an even number, or an odd number?_________ (Choose odd or even) c. If you opened the book to two different pages, would your answers to (a) and (b) be the same’?_________ (Choose yes or no) Answer :odd, even, yes Solution : Opening an actual book and looking at the page numbers will enable students to internalize what this problem means. Books universally start with page 1 on the right-hand side. The right-hand page numbers from there on, therefore, are always odd. The left-hand page numbers are always even numbers. An odd added to an even always gives an odd number. An odd times an even always produces an even number. Help Text : Write answer this form even,even,no respect of option a,b,c. Someone your age has an average pulse rate of 70 beats per minute and is ten years old. This means that, for an average person your age, the heart has already beat about how many times? Round your answer to the nearest hundred million. Answer :400000000 Solution : students can multiply 70 x 60 x 24 x 365 on a calculator, but the display will then be filled on an 8-digit model by 36,792,000. multiplying this by 10 can be done mentally. giving 367,920,000. rounded, the answer 400,000,000 Help Text : write your answer without using (,) comma. Answer form is 123000010
