🧮KG Maths: Counting to 100

If a five-year-old leaves kindergarten knowing every number bond to ten by heart, Grade 1 arithmetic becomes easy. If they leave counting on their fingers, every year afterwards is slower than it needed to be. This course treats bonds to ten as the single non-negotiable outcome and drills them without turning maths into a chore.

Everything is modelled on the ten-frame first, then drawn, then written — the concrete-pictorial-abstract sequence that underpins both Oxford and Singapore-style teaching.

What your child will be able to do

By the end of this course, a learner working at the expected pace will be able to:

• Count forwards and backwards to 100, and in tens
• Recall every number bond to 10 without counting
• Add and subtract within 20 using known facts
• Read and write numerals to 100 and compare them
• Name 2D and 3D shapes and describe their properties

How the course is structured

KG Maths: Counting to 100 is organised into 5 units covering 88 lessons in total, designed to run across 32 weeks at roughly 3 hours a week. The unit outline below shows 20 representative lessons.

Numbers to 20

• The ten-frame and why ten matters
• Teen numbers as ten-and-some-more
• Ordering and comparing to 20
• Odd and even

Number bonds to 10

• Part-whole thinking with counters
• All the pairs that make 10
• Missing-number problems
• Speed practice: bonds in six seconds

Addition and subtraction within 20

• Counting on from the bigger number
• Bridging through ten
• Subtraction as 'difference'
• Word problems with drawings

Numbers to 100

• Tens and ones on a place-value mat
• The hundred square: patterns everywhere
• Counting in 2s, 5s and 10s
• Estimating: about how many?

Shape, measure and data

• 2D shapes and their sides and corners
• 3D shapes: faces, edges, vertices
• Measuring with cubes and then a ruler
• Making a simple block graph

How it is taught

Short daily fluency practice (four minutes) sits alongside one longer teaching lesson. The fluency timer is deliberately generous at first and tightens as your child improves, so the goal always feels reachable.

What is included

• 88 video lessons plus worked examples
• Printable ten-frames, hundred squares and place-value mats
• 22 auto-marked quizzes with instant feedback
• Fluency timer for number-bond practice

Who this course suits

This course sits in the KG track and follows a oxford-aligned sequence. It suits families who want a complete, sequenced mathematics year rather than a set of loose practice activities, and it assumes no teaching experience — every lesson includes a short method note for the adult. If your child is comfortably ahead or behind the beginner level described here, use the placement check in lesson one and start at the recommended point instead of lesson one.
