Goal: represent 61–65, then compare numbers with equal tens. Prepare: six strips, five ones, mat, Day 13 cards.
- Notice, 3: Start with 60 and add one. Ask for the numeral. Key: 61.
- Model, 5: Build 63; point to six tens, three ones and the digit positions. Say/show 60 + 3 = 63. Write 63 and 36, then build one to show why reversal changes the amount.
- Guided, 8: A (art room: six sheets of ten drawn shapes plus two) and B (library display: six rows of ten title cards plus four) are modelled as 62 and 64. Pair the six tens before comparing two versus four ones. Place both on the chart.
- Independent, 6: C (robotics game: six stacks of ten blocks plus five) becomes a chosen model of 65. Learner makes a second model by trading one ten for ten ones: five tens and fifteen ones. Treat the trade as extension; a correct six-tens model meets today's core goal.
- Exit, 3: Show six tens plus one one and six tens plus four ones. Ask which is greater and what each numeral is. Key: 64 > 61. If a child chooses 61 because of its spoken first word, align the equal tens and compare only loose ones.
