2026 Grade 3 Rationalized KLB Lower Primary Mathematical Activities Lesson Plans – Term 3

The Lesson Plans are organized under the following strands and substrands:

• Number Concept
  • Position of objects in number symbols and words – Identifying ordinal positions from 1st to 20th (first to twentieth) in athletic races, queues, and birth order
• Whole Numbers
  • Counting forward and backward in tens from 1 to 1000 using counters and number lines
  • Reading numbers 1 to 1000 in symbols
  • Reading and writing numbers 1 to 100 in words (spelling compound tens: twenty-four, forty-seven, eighty-nine)
  • Number patterns up to 1000 – Determining pattern rules and working out missing numbers
• Addition
  • Adding a 3-digit number to a 2-digit number vertically and horizontally with regrouping from ones to tens (sum not exceeding 1000)
  • Adding two 3-digit numbers without regrouping
  • Adding two 3-digit numbers with regrouping from ones to tens, and from tens to hundreds using place value charts, abacuses, and tins
  • Addition number patterns up to 1000
• Subtraction
  • Subtracting a 3-digit number from a 3-digit number with regrouping from tens to ones
  • Subtracting two 3-digit numbers with regrouping from hundreds to tens
  • Subtraction number patterns up to 1000
• Multiplication and Division
  • Multiplying single-digit numbers by 10 as repeated addition
  • Dividing 2-digit numbers by 2, 3, 4, 5, 6, 7, 8, 9, and 10 without remainders using counters and multiplication table links
• Fractions
  • Eighth as part of a group – Identifying, folding, and shading 1/8 of shapes and sets of objects
• Measurement
  • Length – Adding and subtracting length in metres (m) vertically and horizontally, including classroom measurement drills
  • Mass – Adding and subtracting mass in kilograms (kg) using balances and classroom model shop parcels
  • Capacity – Adding, subtracting, and estimating liquid capacity up to 5 litres (L) using 1-litre containers
  • Time – Adding and subtracting time in hours and minutes without conversion; estimating activity durations in hours; reading and writing time using “minutes past” and “minutes to” the hour on analogue and digital clocks
  • Money – Converting Kenyan currency denominations up to Sh. 1000 (notes and coins); creating 3-item shopping lists, finding total cost, and calculating change/balance
• Geometry
  • Modelling combined shapes – Constructing composite 2D and 3D shapes (e.g., triangle on rectangle, cylinder with cone) using clay, plasticine, and cardboard
