| E1* | Represent and identify numbers to 100 using counters, number lines, ten frames, 100 Chart, drawings, and symbols. |
| E2* | Represent the partitions of two-digit quantities as tens and leftover ones. |
| E3* | Compare quantities and represent that relationship using less than, greater than, between (e.g., intervals), and closer to. |

| E5 | Measure volume using nonstandard units. |

| E7 | Make a bar graph. |
| E8 | Read a table or bar graph to make predictions and solve problems about a data set. |
| E9 | Demonstrate fluency with the addition facts with sums to ten in Group C. |
| E10 | Determine the unknown number in an addition or subtraction sentence relating three whole numbers for the facts with sums to ten in Group C. |
