**Day 1 Teaching**

Use Frog to calculate the likely growth of mice (lengths in cm with 1 decimal place).

**Further teaching with Y6**

Use Frog to subtract numbers with 2 decimal places from whole numbers, then from numbers with 2 decimal places.

**Group Activities**

Y5 -- Use counting back/place value and/or counting up (Frog) to calculate subtractions for numbers with 1 decimal place.

Y6 -- Use counting up (Frog) to calculate differences between numbers with 2 decimal places, e.g. measurements of arm spans.

**Day 2 Teaching**

Use Frog to calculate differences between jumps in metres (2 decimal places). Use a bar model to represent the problem.

**Group Activities**

Y5 -- Use counting up (Frog) to calculate differences between numbers with 2 decimal places, e.g. measurements of arm spans.

Y6 -- Count up to subtract; explore and reason about the choice between column subtraction and counting up for subtracting numbers with 1 or 2 decimal places.

**Day 3 Teaching**

Use Frog to find the difference between two numbers, one with 2 decimal places and the other with 1 decimal place.

**Group Activities**

Use the in-depth problem-solving investigation ‘Talisman squares’ as today’s group activity.

Or, use this investigative activity:

Y5/Y6 -- Whole class investigation. Investigate subtracting numbers with consecutive digits, 9.8 – 7.65, 8.7 – 6.54, 7.6 – 5.43.
