Performance objectives

• Multiply whole numbers by 2-digit number not exceeding 50
• Solves quantitative aptitude problems in volving multiplication of whole numbers by 2-digit numbers
• Multiply decimals numbers by 2-digit numbers
• Solve quantitativeaptitude problems in volving multiplication of decimal numbers by 2 digit numbers.
• Calculate the squares of 1 and 2 digit numbers

Lesson summary

This lesson focuses on expanding learners' understanding and application of multiplication. It builds upon prior knowledge of single-digit multiplication and introduces more complex scenarios involving 2-digit multipliers, decimal numbers, and the foundational concepts of squares and square roots. A solid grasp of these concepts is crucial for everyday life in Nigeria, enabling learners to handle transactions, calculate quantities, understand measurements, and solve practical problems in their homes, schools, and communities. This topic lays the groundwork for more advanced mathematical concepts and problem-solving skills.

Teacher activity

• Begin with a quick revision of basic multiplication facts (up to 10x10) using oral drills or flashcards. Pose a simple word problem that requires multiplication (e.g., "If one pen costs N10, how much do 5 pens cost?"). Elicit responses and relate to real-life transactions.

Evaluation guide

• Observation: Monitor learners' engagement during activities, group discussions, and independent work.
• Oral Questions: Ask targeted questions during lessons to check understanding of concepts and procedures.
• Quick Checks: Have learners complete a few practice problems on mini-whiteboards or scrap paper for immediate feedback.
• Peer-Assessment: Allow learners to briefly check each other's work for simple multiplication and square calculations.
• Instruct learners to answer all questions below.
