PERIOD 1: Assessment

 PRESENTATION TEACHER’S ACTIVITY PUPIL’S ACTIVITY STEP 1ORALASSESSMENTS The teacher asks questions on mental maths treated so far Pupils respond and participate STEP 2DISCUSSION The teacher discusses all the methods used by some learners in the oral assessments(some of the questions are solved on the board by the learners) and addresses any misconceptions that may have risen Pupils pay attention and participate STEP 3WRITTEN ASSESSMENTS 1 Solve 27 + 35 = ___  using a base ten kit and place value table.2. Solve 27 + 35 = ___ using a number line.3. Calculate 27 + 35 = ___ using the column method.4 Circle the method that you found easiest.(Learners circle one of their solutions above. There is not wrong answer here; they might find any of the methods easiest. Ask them to explain their answers verbally if there is time. Answers will vary. E.g. I found the column method easiest because it isquick/ I understand it/ I don’t need to break down 35 into 3, 30 and 2. OR I found the number line method is easiest, because I need less space to work on it, etc. Learners do not have to write the explanation here.) Pupils attempt their class work STEP 4SUMMARY The teacher marks the written assessments, corrects were necessary and commends the pupils

PERIOD 2: Addition with carrying in context

PERIOD 3: Making addition number sentences

PERIOD 4: Assessment
