Description

Are you searching for an engaging math madness activity for your 5th grade students to practice multi-step word problems adding and subtracting decimals? In this Mini Math Madness Mystery Whodunnit Activity your students will practice a mix of operations and comparing with decimals by solving word problem clues in The Case of The Missing Basketballs!

This would make a great Fun Friday activity! Perfect unit to do during the big basketball tournament in March or year round! No mention of a specific time of year!

This fun and highly engaging math mystery activity will motivate your class with a relevant story line, while getting practice working with decimal word problems!

3 companion News Report Videos that enhance the story!

Students will use their math skills to solve The Case of Missing Basketballs! Coach Liam is calling on the expertise of Ellie, Prestyn, and Jr. Detectives to find the missing basketballs in time for the big tournament in March!

Junior Detectives (Students) will analyze the evidence files to solve the clues. Each file contains three clues from the three suspects that were apprehended. Each of the suspects has a story for where they were, but they seem to be hiding something.

There is no order of the files, so Jr. Detectives can start at any file to begin cracking the case with their detective team! Each of the Jr. Detectives will fill out a clue log, and each team will complete their investigation journal.

Jr. Detectives can then check their investigation journal with the Lead Detective (YOU), or they can enter their information into the evidence database (a google form) to reveal the truth behind the disappearance of the basketballs!

With a little prep, you can transform your classroom to a squad room full of junior detectives solving The Case of the Missing Basketballs!

CCSS5.NBT.A.3

Read, write, and compare decimals to thousandths.

CCSS5.NBT.A.3b

Compare two decimals to thousandths based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons.

CCSS5.NBT.B.7

Add, subtract, multiply, and divide decimals to hundredths, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.

CCSSMP1

Make sense of problems and persevere in solving them. Mathematically proficient students start by explaining to themselves the meaning of a problem and looking for entry points to its solution. They analyze givens, constraints, relationships, and goals. They make conjectures about the form and meaning of the solution and plan a solution pathway rather than simply jumping into a solution attempt. They consider analogous problems, and try special cases and simpler forms of the original problem in order to gain insight into its solution. They monitor and evaluate their progress and change course if necessary. Older students might, depending on the context of the problem, transform algebraic expressions or change the viewing window on their graphing calculator to get the information they need. Mathematically proficient students can explain correspondences between equations, verbal descriptions, tables, and graphs or draw diagrams of important features and relationships, graph data, and search for regularity or trends. Younger students might rely on using concrete objects or pictures to help conceptualize and solve a problem. Mathematically proficient students check their answers to problems using a different method, and they continually ask themselves, "Does this make sense?" They can understand the approaches of others to solving complex problems and identify correspondences between different approaches.
