Addition and subtraction within 20 - Compare number sentences - Worksheet

The worksheet from Master the Curriculum focuses on enhancing children's fluency and precision in addition and subtraction within 20. It is designed to encourage students to compare number sentences and determine whether they are greater than, less than, or equal to each other using the symbols <, > or =. The exercises include both abstract numbers and visuals to aid understanding. For example, students might compare whether 13 - 2 is less than, greater than, or equal to 14 - 3. They are prompted to check each calculation, which may not always require a full computation to determine the comparison.

Further activities on the worksheet involve selecting the correct digit to complete a number sentence accurately. This could involve deciding which digit, when subtracted from or added to a number, would make the sentence true. For instance, students must determine which digit makes the sentence 14 - 6 < ____ - 3 correct. The worksheet also incorporates word problems, asking students to apply their reasoning skills. For example, they might have to figure out who has more grapes left, Kai or Jen, after each eats a certain number of their grapes, or who has more marbles after buying additional ones. These problems help students to contextualise their mathematical skills in real-life scenarios.
