Understanding that two-digit numbers are composed of tens and ones using concrete models.

Using mathematical language (greater than, less than, equal to) and symbols to describe the relationship between different magnitudes.

Placing numbers in order from least to greatest and greatest to least using a number line.

Understanding and using ordinal numbers (first, second, third, etc.) to describe position in a sequence.

Exploring the concept of halves by dividing objects and shapes into two equal parts.

Identifying and extending simple number patterns based on addition or subtraction rules.

Moving from counting all to using the 'counting on' strategy for addition within 20.

Recognizing and naming common two-dimensional shapes (squares, circles, triangles, rectangles, hexagons).

Distinguishing between defining attributes (e.g., number of sides, vertices) and non-defining attributes (e.g., color, size, orientation) of 2D shapes.

Recognizing and naming common three-dimensional shapes (cubes, cones, cylinders, spheres, rectangular prisms).

Distinguishing between defining attributes (e.g., faces, edges, vertices) and non-defining attributes of 3D shapes.

Combining smaller shapes to create new composite shapes (e.g., two triangles make a rectangle).

Identifying parts of a whole by decomposing shapes into smaller, simpler shapes.

Dividing circles and rectangles into two and four equal shares, and describing the shares using appropriate language.

Using precise language (e.g., above, below, beside, in front of, behind, next to) to describe the relative position of objects.

Exploring basic geometric transformations (slides, flips, turns) and how they affect the position of shapes.

Identifying and creating lines of symmetry in two-dimensional shapes.

Comparing the lengths of two objects by lining them up side-by-side.

Measuring objects using non-standard units (e.g., paper clips, blocks) and understanding the concept of unit iteration.

Comparing the lengths of two objects by using a third object as a comparison tool.

Reading analog and digital clocks to the hour and understanding the concept of 'o'clock'.

Reading analog and digital clocks to the half-hour and understanding the concept of 'half past'.

Collecting data using tally marks to represent categories of information.

Organizing and representing data with up to three categories using picture graphs.

Asking and answering questions about the total number of data points, how many in each category, and how many more or less are in one category than another.
