Learning Targets for 1st Grade Unit on Place Value of Two-Digit Numbers 1. Knowledge and Simple Understanding

• Students will write two-digit numbers that are represented by drawings, and words, including dimes and pennies, on six problems accurately on paper and/or response boards throughout the unit (Examples: DDDPP = _____, l l l l • = _____,

8 tens and 5 ones = ___).

2. Deep Understanding and Reasoning

• Students will compare values of two two-digit numbers by writing the correct symbols (, =) between them on paper in six number models accurately(Example:

23 61).

• Students accurately will verbally or in writing explain their reasoning for their answer to one number model in which they must write the correct symbol as...
