Shape and Numbers

Overview

In this 20-minute Year 1 session, students will practise counting, comparing numbers, and matching 2D shapes to real-life objects using hands-on materials. They will record their thinking using simple drawings or marks.

Learning intentions

• Students will be able to count objects from 0–20 and show how many.
• Students will be able to compare quantities (more than, fewer than, same).
• Students will be able to identify and sort common 2D shapes (circle, square, triangle, rectangle).
• Students will be able to follow a simple plan to create and check a correct arrangement.

Success criteria

• I can count objects carefully and tell the total.
• I can say which group has more, fewer, or the same.
• I can match shapes to the correct picture/object.
• I can check my work by looking and fixing any mistakes.

Curriculum links

• Mathematics: number and place value (counting and representing quantities).
• Mathematics: measurement and geometry (recognise and sort common 2D shapes).
• Mathematics: using simple representations to communicate ideas.
• Technology connection: plan simple steps, use tools safely, and check outcomes.

Lesson structure (20 minutes)

1. 1 min – Welcome and routine

• Greet the student and quickly recap the materials: counting cards, shape cards, and a small container of objects (e.g., buttons, blocks, paper pieces).
• Tell the student they will “count, compare, and match shapes” today.

2. 4 min – Count and show how many

• Place 10–15 objects on the table (adjust for the student’s comfort, aiming for a short but meaningful range).
• Ask the student to count aloud, touch each object once, and then stop when finished.
• Record the number on a sticky note or whiteboard with one clear number and/or tally marks.

3. 4 min – Compare quantities

• Create two small groups of objects: Group A (e.g., 7) and Group B (e.g., 9). Keep differences obvious but not too large.
• Ask: “Which group has more? Which group has fewer? Are they the same?”
• Invite the student to count both groups to justify their answer.

4. 6 min – Sort and match 2D shapes (hands-on)

• Place picture cards or outline shape cards for circle, square, triangle, rectangle.
• Give the student shape cut-outs and/or small objects with flat faces (e.g., a coaster circle, card square).
• Ask the student to sort into four piles, then match each pile to the correct shape card.
• After sorting, ask the student to point to one shape and name it.

5. 4 min – Create a simple ‘shape number’ arrangement

• Provide a small grid (e.g., 2x2 or a line of 5 spaces) on paper or a mat.
• Task: “Put the shapes in order” by making a pattern using numbers and shapes. Example:
• “Place 3 circles and 2 squares next to each other,” or
• “Make a line: square, triangle, square, triangle, square.”
• The student should do the arrangement, then check by counting the shapes placed.

6. 1 min – Quick reflection and exit

• Ask two quick questions:
• “How many did you make?”
• “Which shape was easiest/hardest to match?”
• Praise effort and confirm the student’s next step.

Resources

• Counting objects (buttons, bottle tops, blocks, or paper counters)
• Shape cards for circle, square, triangle, rectangle
• Shape cut-outs and/or flat-shape samples
• Small container or tray to keep materials organised
• Whiteboard/mini board and marker (or sticky notes)
• Pencil and paper for quick recording (number and/or drawing)
• Optional: a simple 2x2 grid or 5-space line template
• Timer/clock visible to the teacher

Assessment

• Observe counting accuracy (one-to-one correspondence) and whether the student can state the total.
• Listen for correct use of comparison language: more than, fewer than, same as.
• Check whether the student correctly matches/sorts the four 2D shapes and can name at least one shape.

Differentiation

• Support:
• Use fewer objects (0–10) if counting is difficult, and increase only when ready.
• Provide sentence starters: “This group has ___.” “This one has more/fewer.”
• Offer physical guidance by pointing to each object as it is counted.
• Extension:
• Increase the range (up to 20) and ask the student to compare using a “how many more?” idea.
• Add another shape (e.g., oval) only if the student is confidently naming the four core shapes.
• EAL/SEN:
• Keep language consistent and repeat key words (circle, square, triangle, rectangle, more, fewer, same).
• Use visual supports: picture cards for numbers, gesture-based counting, and labelled piles.
• Independence:
• If ready, remove the teacher model and ask the student to create the arrangement independently, then self-check by counting.
