STOP 1-by - 1 COUNTING! Build True Teen Number Fluency & Place Value Sense Instantly!

Are you struggling to help your students move past counting by ones for teen numbers? Transitioning from counting to conceptual subitizing is the key to mastering Place Value. This research-backed, Science of Math approved routine is designed to help students “see” the 1 0 within every teen number.

This interactive resource for Power Point & Google Slides focuses exclusively on Numbers 1 1-2 0. Designed for high-impact use on Smart boards and Interactive White boards, this zero-prep routine forces the brain to capture quantities in under 3-5 seconds, anchoring every number to the benchmark of 10.

WHY THIS 1 1 - 2 0 ROUTINE IS ESSENTIAL:

Place Value Foundations: Uses dual-structured circle models to explicitly show “10 and some more,” building the mental architecture for addition and subtraction.

Visual Decomposition: Clean, color-coded answer slides (Blue for tens, Green for ones) with explicit thinking sentences (e.g., “I see 10 and 4, that makes 1 4”).

Metacognitive Strategy: Built-in “How did you know?” prompts to encourage students to explain their grouping strategies.

Inclusive Design: 1 0 0% distraction-free, high-contrast layouts —perfect for A D H D, Autism, and SEN classrooms.

WHAT’S INCLUDED:

4 5 Interactive Subitizing Slides: Featuring structured arrangements that emphasize the base-1 0 system.

Power Point & Google Slides Versions: Fully editable and ready to use on any device.

Teacher Instruction Guide: A step-by-step framework to run this as a seamless 5-minute daily math warm-up.

CURRICULUM ALIGNMENT:

E Y F S (UK): Mathematics - Numerical Patterns (Understand the ‘One more than’ relationship between consecutive numbers).

Common Core (US): K.N B T.A.1 (Work with numbers 1 1-1 9 to gain foundations for place value).
