Work Sample Outcomes:
NS2.1- Counts, orders, reads and records numbers up to four digits.
NS2.2- Uses mental and written strategies for addition and subtraction involving two, three and four digit numbers.
Work Sample Task:
Student is asked to solve problems in their head (mentally) and record the strategy that they used. The problems were;
34+17
73-35
63+29
162-69
Possible indicators from work sample: 1. Reads, writes and says three and four digit numbers. 2. Records three and four digit numbers using expanded notation. 3. Explains and records methods for adding and subtracting. 4. Uses split strategy for addition and subtraction.
Are indicators achieved or not: 1. Hard to determine but looking at the work sample would determine that the student can read, write and say three digit and four digit numbers. (yes) 2. The student can explain and record methods for adding and subtracting but is not using the correct …show more content…
* Uses the formal written algorithm to solve addition and subtraction.DS2.1- Gathers and organises data, displays data using tables and graphs, and interprets the results. * Interprets information presented in a given column graph or picture graph.WMS2.4- Checks the accuracy of a statement and explains the reasoning used. * Compares tables and graphs constructed from the same data to determine which is the most appropriate method of display is. Reasoning | In this lesson the learners will:Show their knowledge of addition and subtraction using three and four digit numbers whilst interpreting given data from column and picture graphs.Compare different graphs and determine which graph is more suitable for the method of display.Interpret results given through column and picture graphs.
