• Description:

  Download high-quality, editable Grade 1 Rationalized Mathematical Activities Term 3 Lesson Plans 2026 - KLB Lower Primary prepared in strict conformity with the rationalized Competency-Based Curriculum guidelines. The PDF version is also available upon your request. This comprehensive, downloadable MS Word document contains 35 expertly prepared lessons across 7 weeks, mapped directly to the KLB Lower Primary Mathematics Pupil’s Book 1 (pages 136–168) and Teacher’s Guide (pages 6–60).

  The lesson plans provide thorough coverage of foundational mathematics strands, substrands, and practical concepts:

  • Numbers and Whole Numbers
    • Pre-Number Activities: Sorting and matching concrete objects by texture (rough and smooth) and creating repeating patterns using objects of different sizes.
    • Counting and Place Value: Rote and one-to-one counting forward up to 50, counting backward from 30 down to 1, representing numbers 1 to 30 using concrete counters and quantity tables, reading and writing numerals 1 to 50, and reading and writing number words from "one" to "ten".
  • Operations (Addition and Subtraction)
    • Addition: Adding a 2-digit number to a 1-digit number without regrouping horizontally and vertically with sums up to 40 and 50 using counters, abacus, and place value charts; working out missing numbers in increasing patterns (+1 and +2).
    • Subtraction: Subtracting a 1-digit number from a 2-digit number (10 to 50) without regrouping, solving everyday word problems, and identifying missing numbers in decreasing patterns (-1 and -2).
  • Measurement
    • Length, Mass, and Capacity: Measuring length using arbitrary units (hand spans, walking steps, sticks); comparing and measuring mass using simple beam balances; measuring and transferring liquids across containers to understand volume conservation.
    • Time and Money: Identifying the 12 months of the year chronologically; identifying the Kenyan 50 shillings currency note; role-playing classroom shop transactions to buy 1 and 2 items up to sh. 50 with exact money without balance.
  • Geometry and Revision
    • Lines and Shapes: Drawing straight lines with rulers, drawing curved lines freehand, and creating repeating geometric patterns using cut-outs of rectangles, circles, and triangles.
    • Term Revision: Systematic review exercises covering numbers, operations, arbitrary measurements, currency, lines, and 2D shapes in preparation for end-of-term assessments.

  Every lesson plan incorporates a 5-minute introductory hook, 25 minutes of step-by-step lesson development, a 10-minute concluding synthesis, extended home activities, and teacher self-evaluation entries. The plans emphasize core competencies such as critical thinking, numeracy, digital literacy, and financial awareness through active manipulation of counters, abacuses, number flashcards, specimen money, and measuring tools.
