Maths Year 2 Autumn Place Value

Each unit has everything you need to teach a set of related skills and concepts. 'Teaching for Understanding' provides whole-class teaching and fully differentiated adult-led group activities. ‘Problem-solving and Reasoning’ develops these skills, and includes questions to enable you to assess mastery. Practice sheets ensure procedural fluency. Extra support activities enable targeted work with children who are well below ARE.

‘UNIT PLAN’ gives you a text version of all parts of the unit to use in your school planning documentation. ‘DOWNLOAD ALL FILES’ gives you that unit plan plus all of associated documents. These bulk downloads are added value for Hamilton Friends and School Subscribers.

Unit 1 Count to 100, identify number, estimate (suggested as 2 days)

Objectives

Count to 100, identify number, estimate
Unit 1: ID# 2113

National Curriculum
Num/PV (iii) (iv) (v)

Hamilton Objectives
3. Identify any number on 1-100 grid; understand that each is a multiple of 10 and some 1s.
4. Locate any 2-digit number on a 1-100 grid or a landmarked line; use this to order and compare numbers.
5. Read and write numbers to at least 100 in numerals; make recognisable attempts to write in words.

Teaching and Group Activities for Understanding

Day 1 Teaching
Use a 1-100 bead bar to show children how to locate 2-digit numbers by identifying the 10s either side. Children repeat on bead strings. Then demonstrate locating and writing numbers on a beaded number line and a landmarked number line.
Group activities
Use the in-depth problem-solving investigation ‘100 Square Jigsaw’ from NRICH as today’s group activity.
Or, use these activities:
-- Most children roll two 1-10 or 0-9 dice to generate two random 2-digit numbers, which they mark on a beaded line. They compare these pairs of numbers.
-- Some children identify multiples of 10 that a third random number lies between.

Day 2 Teaching
Show a quantity of supermarket vouchers and ask children to estimate within a range and to the nearest 10. Model how to count the vouchers efficiently by grouping in 10s, or 5s for smaller numbers.
Group activities
-- Children use pasta shapes in mugs to estimate quantities, then count efficiently by grouping into 10s.

You Will Need

  • 0-100 bead bar, tags & bead strings
  • Additional activity sheets (see resources)
  • About 170 supermarket vouchers
  • Small sorting hoops or plates

Teaching and Group Activities for Understanding

Day 1 Teaching
Use a bead bar. Cover the first 5 beads with a cloth, point out the 5 that are visible, and count in 10s from 5 by sliding 10 beads along each time. Repeat, starting with other 1-digit numbers.
Group activities

Day 2 Teaching
Use a bead bar to show a number of beads. Demonstrate partitioning into 10s and 1s to aid counting. Repeat.
Group activities
-- Children work in pairs to make a 2-digit number and record their numbers in a number sentence, e.g. 68 = 60+8, or 42p = 40p + 2p, showing understanding of partitioning.

Day 3 Teaching
Rehearse finding 2-digit numbers on a bead bar and reading these as some 10s and 1s. Then use PV cards to rehearse PV additions, e.g. 40 + 5 = 45, and subtractions.
Group activities
