Learning Objectives

Indicator: B1.1.1.1.4 - Use comparative language to describe the relationship between quantities/numbers up to 100 using place value and the number line

By the end of the lesson, learners can:

Compare two groups of objects (up to 100 objects) using 1-to-1 correspondence or matching and identify which group has “more than”, “less than”, or “the same as” the other.
Use the terms “more than”, “less than”, and “the same as” correctly when describing the relationship between two quantities or numbers up to 100.
Put groups of objects or numbers (between 1 and 50) in increasing or decreasing order and explain how they found the order.
Identify the number that is 1 more or 1 less than a given number up to 100.
Use a number line from 0 to 100 to compare and order whole numbers, explaining their reasoning using comparative language.

Exemplars (from the NaCCA curriculum)

E.g. 1. Use 1-to-1 correspondence or matching to solve problems that involve comparing 2 sets having between 1 to 100 objects and explain how he/she solved the problem (finding which set has more or less, which groups have the same as)
E.g. 2. Use the terms "more than", "less than" or "the same as" when comparing two groups having between1 to 100 objects
E.g. 3. Put groups between 1 to 50 objects in increasing or decreasing order and justify his/her answer or explain what he/she did to find the answer
E.g. 4. Identify numbers and groups of objects that are that are 1 more or less than a number (for numbers 1 to 100
E.g. 5 Use the number line to compare and order whole numbers from 0 to 100
