Standards Covered
- MNU 2-01aCurriculum for Excellence · Math · Early Level (P1) · KindergartenI can use my knowledge of rounding to routinely estimate the answer to a problem then, after calculating, decide if my answer is reasonable, sharing my solution with others.
- MNU 2-02aCurriculum for Excellence · Math · Early Level (P1) · KindergartenI have extended the range of whole numbers I can work with and having explored how decimal fractions are constructed, can explain the link between a digit, its place and its value.
- MNU 2-03aCurriculum for Excellence · Math · Early Level (P1) · KindergartenHaving determined which calculations are needed, I can solve problems involving whole numbers using a range of methods, sharing my approaches and solutions with others.
