This is designed as a math review. Students navigate around the room spotting 10 crimes again math! They use their recording sheet to identify the crime, correct it, and issue a fine. This is perfect do with crime scene tape, cop hats, and badges. It's a great way to make review fun and exciting while also examining common errors in math and problem solving.
The problems in this standard cover multiplication, addition and subtraction, and graphs.
The first 4 pages are recording sheets. The final 10 are word problems with incorrect thinking. Students correct the incorrect thinking on the recording sheet.
Standards for the word problems:
NC.3.MD.3 Represent and interpret scaled picture and bar graphs: • Collect data by asking a question that yields data in up to four categories. • Make a representation of data and interpret data in a frequency table, scaled picture graph, and/or scaled bar graph with axes provided. • Solve one and two-step “how many more” and “how many less” problems using information from these graphs
NC.3.OA.1 For products of whole numbers with two factors up to and including 10: • Interpret the factors as representing the number of equal groups and the number of objects in each group. • Illustrate and explain strategies including arrays, repeated addition, decomposing a factor, and applying the commutative and associative properties.
NC.3.OA.2 For whole-number quotients of whole numbers with a one-digit divisor and a one-digit quotient: • Interpret the divisor and quotient in a division equation as representing the number of equal groups and the number of objects in each group. • Illustrate and explain strategies including arrays, repeated addition or subtraction, and decomposing a factor.
NC.3.OA.3 Represent, interpret, and solve one-step problems involving multiplication and division. • Solve multiplication word problems with factors up to and including 10. Represent the problem using arrays, pictures, and/or equations with a symbol for the unknown number to represent the problem. • Solve division word problems with a divisor and quotient up to and including 10.
NC.3.NBT.2 Add and subtract whole numbers up to and including 1000. ● Use estimation strategies to assess reasonableness of answers. ● Model and explain how the relationship between addition and subtraction can be applied to solve addition and subtraction problems. ● Use expanded form to decompose numbers and then find sums and differences.
