 STOCKBRIDGE COUNTS – ADDITION & SUBTRACTION

OUR CURRENT FOCUS ACROSS THE SCHOOL IS ADDITION AND SUBTRACTION

From Monday 17th April to Friday 25th May

What will this look like for my child?

Addition and subtraction within Early Level (Nursery and P1, but earlier or later for some)

• Count items in one collection
• Establish a collection of a given numerosity (e.g. get me 6 counters from the group)
• Count items in two collections
• Count items in two collections
• With first collection screened
• With second collection screened
• With both collections screened
• Explore adding using a count-on strategy
• Explore doubles and near doubles
• Know doubles (1 to 5)

Addition and subtraction within First Level (P2, P3 & P4, but earlier or later for some)

• Add using a count-on strategy
• Subtract using a count-on or count-back strategy (e.g for 5 – 3, count on from 3 to 5 or count back from 5 to 3)
• Use doubles (and near doubles) in addition sums
• Add numbers to 20 using number bond facts, bridging through ten, doubles and near-doubles
• Subtract numbers to 20 using counting back, number bond facts, bridging through tens
• Add 3 numbers together (e.g. 7 + 2 + 6)
• Know and use addition and subtraction family facts (e.g. 6+3=9, 3+6=9, 9-3=6, 9-6=3)
• Add on multiples of ten to a 2-digit number (e.g. 45 + 20)
• Subtract multiples of ten from a 2-digit number (e.g. 72 – 40)
• Add tens and units with no regrouping (e.g. 34 + 21)
• Subtract tens and units with no regrouping (e.g. 76 – 35)
• Add tens and units with regrouping (e.g. 65 + 27)

Subtract tens and units with regrouping (e.g. 51 – 38)

Addition and subtraction within Second Level (P5, P6 & P7, but earlier or later for some)

• Add and subtract 2-digit numbers using a variety of strategies
• Add and subtract multiples of ten and hundred (e.g. 300 + 520)
• Use a variety of strategies to find a pair of numbers that add to make 100 (e.g. “What goes with 63 to make 100?”)
• Add and subtract 3-digit numbers using a variety of mental/written strategies e.g. 477+8, 534+40, 624-200 (mental) and 751-36, 621+185 (written)
• Identify the number partner to go with a decimal tenth to make one (e.g. “What goes with 0.3 to make 1?”)
• Identify the number partner to go with a decimal hundredth to make one (e.g. “What goes with 0.37 to make 1?”)
• Add and subtract decimal numbers using a variety of (written) strategies
• Add and subtract simple fractions e.g. ½ + ¼
