About this lesson and its coverage
Original Model Test for Exam unit. These questions and suggested practice times are independent Kidemy material, not an official or past paper. Choose modules for the target programme; all listed subjects are not required for every applicant.
Learn the idea
Read what is known and what is being asked. Use place value in written operations. Equal groups connect multiplication and division. A fraction needs equal parts of a defined whole. A final number without its unit or explanation may not answer the question.
Worked example
Four boxes contain 6 pencils each. Total = 4×6 = 24 pencils. Sharing 24 among 3 children gives 8 each. Half of the 24 pencils is 12.
- Write the operation before calculating.
- Show a check or drawing.
- State the answer with its unit.
