E3 |
Show and recognize different partitions of
multidigit numbers using different representations
(e.g., |

E8 |
Estimate sums and differences using mental math strategies (e.g., rounding using benchmarks, using friendly numbers, composing and decomposing numbers, counting). (Algebra 4) [2.NBT.8, 9] [MP2, 3, 5, 6] | |||||||||||||||||||
Math Facts |
||||||||||||||||||||
Number 3 Computation and Estimation: Use efficient and flexible procedures to compute accurately and make reasonable estimates. |
||||||||||||||||||||
E9 |
Demonstrate fluency with the subtraction facts related to the addition facts in
Group F (14 − 4, |
|||||||||||||||||||
E10 |
Determine the unknown number in an addition or subtraction sentence relating three whole numbers for the facts in Group F. (Algebra 4) [2.OA.1] [MP2] | |||||||||||||||||||
Math Practices |
||||||||||||||||||||
MPE1 | Know the problem. I read the problem carefully. I know the questions to answer and what information is important. (Algebra 4) [MP1, 2, 3] | |||||||||||||||||||
MPE2 | Find a strategy. I choose good tools and an efficient strategy for solving the problem. (Algebra 4) [MP1, 2, 3, 5, 8] | |||||||||||||||||||
MPE3 | Check for reasonableness. I look back at my solution to see if my answer makes sense. If it does not, I try again. (Algebra 4) [MP2, 3, 6] | |||||||||||||||||||
MPE4 | Check my calculations. If I make mistakes, I correct them. (Algebra 4) [MP6] | |||||||||||||||||||
MPE5 | Show my work. I show or tell how I arrived at my answer so someone else can understand my thinking. (Algebra 4) [MP2, 3, 5] | |||||||||||||||||||
MPE6 | Use labels. I use labels to show what numbers mean. (Algebra 4) [MP6] |
