The Year 2 Bonds to 100 (Tens) PowerPoint guides both teachers and children through the lesson, including use of the varied fluency, reasoning and problem solving, deeper reasoning and scaffolded resources. Key learning information about this step:
Key Vocabulary
number bonds: Two numbers that join together to make a different whole number.
ones: Individual units that make up a whole number.
tens: A group of 10 ones together is the same as 1 ten.
multiples of 10: Counting in groups of 10. The ones digit will always be a 0.
Varied Fluency
Knowledge Organiser
• Designed to support all children via key information and examples.
For the purple sections of the four levels, copy and paste these from the first sheet of the varied fluency resource.
Scaffolded Examples
• Counting counters on a ten frame then shaded rows on a hundred square; building up to using a bond to 10 to find the matching bond to 100
Support
• Q1: complete the bond to 10 and the matching bond to 100; with a ten frame to support.
• Q2: complete the bond to 100 shown by a shaded hundred square; first number given, find the missing second number.
• Q3: complete the part-whole model and bond to 100, first number given, find the missing second number.
Core
• Q1: complete the bond to 10 and the matching bond to 100.
• Q2: complete both parts of the bond to 100 shown by a shaded hundred square.
• Q3: complete the missing part in a part-whole model and both parts of the bond to 100.
Stretch
• Q1: find the missing first number in a bond to 10 and in the matching bond to 100.
• Q2: find two ways to express the bond to 100 shown by a shaded hundred square.
• Q3: find the missing part in a part-whole model, then find two ways to express the bond to 100.
Reasoning and Problem Solving
Support
• Q1: Reasoning – decide whether a character is correct about a bond to 100 found from a bond to 10; use a ten frame to support.
• Q2: Problem Solving – arrange picture cards showing tens to find two pairs that total 100, from five cards where one card has no pair.
• Q3: Problem Solving – find two multiples of 10 that make 100, with the first number restricted to a narrow range; find two possibilities.
Core
• Q1: Reasoning – decide whether a character is correct about a bond to 100 found from a bond to 10.
• Q2: Problem Solving – arrange a mix of numeral and picture cards to find two pairs that total 100, from five cards where one card has no pair.
• Q3: Problem Solving – find two multiples of 10 that make 100, with the first number restricted to a wider range; find three possibilities.
Stretch
• Q1: Reasoning – decide whether a character is correct about a bond to 100 described in tens, with no bond to 10 given.
• Q2: Problem Solving – arrange numeral cards, including 100 and 0, to find two pairs that total 100, from five cards where one card has no pair.
• Q3: Problem Solving – find two multiples of 10 that make 100, with the first number given a wide range; find all the possibilities.
Deeper Reasoning
The question in this set focuses on investigating possible values using row and column totals to deepen understanding in recalling and using addition and subtraction facts to 20 fluently, and deriving and using related facts up to 100.
