Four Operations with Decimals Mixed Practice B

Use these after the separate operation pages. Have your child circle each sign before solving and estimate when a problem looks big. Treat the error analysis and puzzle pages as discussion pages: ask how they knew an answer was wrong.

Add, subtract, multiply and divide decimals with a new mix of problems (set B). A decimal is a number with a point. Line up the points to add and subtract, count places to multiply, and move both points to divide by a decimal. The directions on the page read: Look at the sign in each problem. Then, solve it in the box and write the answer. The answer key shows every answer.

Yes, both. We made it for 5th Grade decimals, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with mixed decimal operations and review. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

They read the sign first. Line up the points to add and subtract, count decimal places to multiply, and move both points to make the divisor whole to divide. Mixed sets build the habit of checking the sign before starting.

Students read a worked solution with one mistake, find the first wrong step and fix the answer. Spotting a misplaced point in someone else's work makes students check their own more carefully.

The two mixed skills reviews and the chapter review cover place value, rounding, comparing, all four operations and word problems, so they show which skills still need practice.

Most pages support CCSS 5.NBT.B.7 (four operations with decimals). The order of operations page supports 5.OA.A.1, and the mixed skills reviews include 5.NBT.A.3 and 5.NBT.A.4.

5th graders read, write, compare and round decimals to thousandths (CCSS 5.NBT.A.3 and 5.NBT.A.4), understand place value patterns and powers of 10 (5.NBT.A.1 and 5.NBT.A.2), and add, subtract, multiply and divide decimals to hundredths (5.NBT.B.7).

Start with place value to thousandths, then comparing, ordering and rounding. Move to adding and subtracting, then multiplying and dividing. Finish with word problems, mixed operations and a unit review. The subtopics on this page follow that order.

Estimate first. Rounding each number to a whole number gives a ballpark answer, so 4.8 x 3.1 should be about 15, which rules out 1.488 and 148.8.

Yes. All 55 sheets have an answer key, and the two page sheets have a two page key.
