Problem Solving Unit I have created a unit of work containing 56 problems using problems from the invaluable. Guess Number Blue Jays Diamondbacks Red Sox Total First Guess 10 20 10 40 Second Guess 20 40 10 70 Now guess a greater number of Blue Jays. In research the solution is often unknown, so checking solutions is a critical part of the process. Guided Practice Have students try solving this problem using the strategy of Guess and Check. How Can You Stretch Students' Thinking? Check by working out the name together. The activities are open-ended and encourage your students to think and work mathematically.

Divide these into 10 equal groups. Place them face down in rows. Exploring Fractions 59 Where are the tenths? Together make a new shape. What is the total number of plants in the garden? The blackline master provided sets out a sequence for students to work through when implementing the new skill. Laminate them for reuse in small group activities.

Students can physically move around the room to indicate their real-life responses to the generalization. The language is simple and easy-to-follow. Students can use patterns in the problem or in their guesses to determine the correct guess. Each unit in Solve That Problem! Each book contains a wealth of activities, blackline masters and assessment tasks for a whole life-time of teaching. Bev is a passionate believer in fun, practical resources which help teachers make maths lessons a highlight of the day. Decorate to make a colourful halves pattern. Try sorting from the largest to the smallest piece too! Which 2 cards go together to make one whole pizza? By playing games with fractions, by talking about them with a partner, by actively cutting, tearing, drawing or sharing fractional parts, your students will see how easy fractions are to construct, compare and order.

Page 1 of 2 Problem Solving: Guess and Check What Is It? Demonstrate how to write a paragraph describing the steps and how decisions were made throughout the process. For example, the problem: Ben knows 100 baseball players by name. Most importantly the students enjoyed it and looked forward to it each week. The unit contains eight questions and answers for each of the following strategies, Act it Out, Draw a Diagram, Guess and Check, Logical Reasoning, Look for a Pattern, Using Simpler Numbers and Work Backwards. Each unit is packed with enough activities for small groups, or a whole class, to explore for at least a week. There are plenty of photocopiable playing cards, activity cards and worksheets. Of 25 rounds at the regional spelling contest, the Mighty Brains tied 3 rounds and won 2 more than they lost.

How do you know what name to give this piece? This involves finding the key pieces of information needed to find the answer. By asking questions and active discovery, children learn to enjoy using mathematics as part of their everyday lives. Outcomes Indicator Record The complete list of learning outcomes is available on page 92. Find a way to divide each set into tenths. The students write a full sentence explaining what they are trying to find out. Have students justify their answers. This mathematics program was a tremendous success and dramatically improved the mathematical reasoning and problem solving of the students I taught.

Try to collect the most matching pairs. Strategy: The students write the strategy they are going to use. A number of years ago I was introduced to the concept of teaching formalized problem solving strategies to elementary aged children. About the author Originally a primary school teacher, Bev Dunbar is now actively involved in teacher education as a Mathematics Consultant and University Lecturer in Mathematics Education working in both the State and Catholic Education systems. The rest are Blue Jays and Diamondbacks.

Guess and Check A method of solving problems by making guesses and checking them. You may want to set up a table to record the guesses. See page 93 for examples of how to organise a 40 week term for Mathematics in your classroom. Then, problems can be acted out by actual students, who may utilize props or manipulatives to illustrate what is taking place in the problem. Middle Primary introduces a new problem-solving skill, following a structured sequence. All research mathematicians use guess and check, and it is one of the most powerful methods of solving differential equations, which are equations involving an unknown function and its derivatives.

Each piece is one of 2 equal pieces. The other players close their eyes, while the leader sorts the leaves between the koalas. Use this to record individual student progress. With your partner, guess how many dots in 1 tenth of these dots. Decide on the number of columns to fit the variables.
