In reception the children should be taught steps 1 - double 1 and double 2 in term 1 and their ability to answer quickly is checked by a weekly 20 second Beat That “test” If they master that they move onto Step 2 - double 3, 4 and 5 and it’s checked by a 20 second test which covers Steps 1 and 2. When they master that they move onto step 3 and a 20 second test which covers steps 1, 2 and 3. That’s Reception.
In Y1 term 1 children are taught step 4 - 1+9=10,2+8=10,3+7=10,4+6=10 and 5+5=10. Another 20 second test cover steps 2,3&4. In term 2 they are taught Step 5 2+4,2+5,2+6,2+7,2+8,2+9,3+4, 3+5 and 3+6 and tested on steps 3, 4 and 5 (30 seconds). In term 3 they are taught Step 6 - double 6,7,8 and 9 and tested on steps 4, 5 and 6. (30 seconds)
In Y2 term 1 they are taught Step 7 - 3+8, 3+9, 4+7, 4+8, 4+9 and the 20 times table and tested on steps 5, 6 and 7 (30 seconds). Term 2 - 5+4, 5+6, 6+7, 8+7, 8+9 and the 5 times table and are tested on. Steps 6, 7 and 8 69 seconds. Term 3 they are taught 5+7, 5+8, 5+9, 6+9, 7+9, 8+9 and the 2 times table and tested on steps 7, 8 and 9 (basically a times table test)
In year 3 the 3, 4 and 8 times tables are taught steps 10, 11 and 12.
In year 4 6x6, 6x7, 6x9, 7x7, 7x9 and 9x9 (six fact challenge) basically the only six multiplication facts up to 10 times tables not covered by previous learning. In term 2 11 times tables and term 3 12 times tables. Steps 13, 14 and 15.
At that point holder should know all the addition and multiplication facts they need to complete any calculation.
