Combine two small groups of items (from 1 to 3) to find a total that is less than 5.
Join two or three groups of items (from 1 to 8 in each group) to find a total that is less than 10.
Add two or three numbers (ranging from 0 to 9) to get a sum not exceeding 18.
Add two-digit numbers (e.g., 10 + 20) without needing to carry over numbers, to obtain a total not greater than 40.
Write their addition answers clearly and check their work to ensure accuracy and readability.
Lesson summary
This topic, "Addition I," introduces Primary 1 learners to the fundamental concept of combining quantities. Addition is a core mathematical operation essential for daily living and forms the basis for more complex arithmetic. In the Nigerian context, understanding addition is crucial for learners to perform simple transactions, count resources (e.g., agricultural produce, livestock), manage personal belongings, and participate in communal activities requiring counting and combining.
Teacher activity
Guides pupils to group the objects in to on es, twos, threes and fours to form sum less than 5 e.g. 2 balls and 2 pencils give 4 balls.
Groups objects up to nine to form sum less than
e.g. 5 or anges and 2 or anges gives 7 or anges.
Groups objects from 1 to 9 with sum not greater than 18 e.g. 9 bean seed and 8 bean seed gives 17 bean seeds.
Evaluation guide
Assessment will be continuous throughout the lesson (formative) and at the end (summative).
1 Formative Assessment:
Observation: Observe students during group activities and individual practice for participation, understanding of concepts, and use of strategies.
Question and Answer: Ask direct questions to assess understanding of basic addition facts and vocabulary.
Whiteboard/Slate Work: Have students solve problems on personal whiteboards or slates for quick checks.
