# Mathematics

## Proficiencies

**Understanding** includes connecting names, numerals and quantities.

**Fluency** includes readily counting numbers in sequences, continuing patterns and comparing the lengths of objects.

**Problem Solving** includes using materials to model authentic problems, sorting objects, using familiar counting sequences to solve unfamiliar problems and discussing the reasonableness of the answer.

**Reasoning** includes explaining comparisons of quantities, creating patterns and explaining processes for indirect comparison of length.

## Achievement Standard

By the end of the year the students are expected to:

**Number and Algebra**

- connect number names and numerals with sets of up to 20 elements;
- estimate the size of these sets;
- use counting strategies to solve problems that involve comparing, combining and separating these sets;
- match individual objects with counting sequences up to and back from 20;
- order the first 10 elements of a set.

**Measurement and Geometry**

- identify measurement attributes in practical situations and compare lengths, masses and capacities of familiar objects;
- order events, explain their duration and match days of the week to familiar events;
- identify simple shapes in their environment and sort shapes by their common and distinctive features;
- use simple statements and gestures to describe location.

**Statistics and Probability**

- sort familiar categorical data into sets and use these to answer yes/no questions and make simple true/false statements about the data.
