Learning Objectives

Indicator: B3.1.1.1.4 - Compare and order whole numbers up to 10,000 and represent comparisons using the symbols >, <, or =.

By the end of the lesson, learners can:

Compare two whole numbers up to 10,000 and describe which is bigger or smaller using place value reasoning (comparing digits in the thousands place first, then hundreds, then tens, then ones).
Represent comparisons between two numbers correctly using the symbols >, <, or =.
Arrange a small group of numbers (up to five numbers) in increasing or decreasing order up to 10,000 and justify the order using place value.
Identify and correct missing numbers or errors on a number line or hundreds chart section from 100 to 10,000.
Solve simple word problems involving comparison of quantities up to 1,000, explaining their reasoning clearly.

Exemplars (from the NaCCA curriculum)

E.g. 1. Demonstrate an understanding of how place value determines the relative size of whole numbers (between 100 and 10,000) by:
- describing the relative size of two numbers (i.e., saying whether one number is a little or a lot bigger or smaller than another and justifying the answer)
- identifying which of two given numbers is bigger (or smaller), explaining why using place value and representing the relationship using the symbols< and >;
- putting a small group of numbers in increasing or decreasing order and justifying the order using a hundreds frame, a number line or place value;
- identifying the missing numbers or errors in a section of number line from 100 to 10,000 or in a hundreds chart and justifying the answer using place value
- solving word problems that involve comparing quantities to 1000 (i.e., Agbo has 230 chickens. Dzifa has 460. What can you say?)
