Math Mammoth Discovery Word Problems is intended for students in 4th grade and above that need more practice with word problems. I especially aim to help students in grades 4-7 who have trouble with word problems and who may need to 'go almost back to the beginning,' so to speak, to learn to solve them.The skills covered include addition, subtraction, multiplication, division, large numbers, divisibility, units of measurement, bar models in problem solving, average, geometry, fractions, and decimals. The problems require knowledge of fourth grade math, such as long division, long multiplication, knowledge of basic measurement units, and the usage of several operations. However, there are only a few worksheets dedicated to fractions and decimals, and the problems in general do not require calculations with fractions or decimals, with the exception of money amounts.The book presents a variety of situations - many of them about animals and farming - so that students will have some fun as they look for and discover the solutions. Mathy the Mammoth, with his obsession with blueberries, is featured several times, and students will also go hiking and traveling around the world. There are also some challenging word problems (marked as such) and interesting puzzle corners.Some worksheets have examples and some instruction related to problem solving. Students are often encouraged to write down the calculations they do. I suggest that you also encourage your student(s) to make a drawing or a sketch of the situation in the problem (if applicable), to help them understand the situation and to see what math operation is involved.Overall, the problems in this collection require multiple steps, with the exception of question #1 in worksheet 'Division Warm-Up', as it focuses on differentiating what math operation should be used.
