Inhoud

Aktiwiteit: om getalle voor te stel, te herken en te vergelyk [lo 1.3]

Om korrek te kan bereken [lo 1.8]

Om vaardighede in hoofreken te verbeter [lo 1.9]

1. As jy jou tafels baie goed ken, is dit baie makliker om te vermenigvuldig en te deel, veral met groter getalle. Werk saam met ‘n maat. Kyk hoe vinnig julle die korrekte visse wat by die x-tafels pas, kan vang deur dit netjies in te kleur.

1.1 8× tafel - groen

1.2 9× tafel - blou

1.3 12× tafel - geel

2. Kom ons kyk nou eers of jy jou vaardighede in hoofreken kan verbeter! Werk op jou eie en voltooi die volgende hoofrekentoets so vinnig en korrek moontlik! In Wiskunde beteken hakies: “doen daardie stukkie eerste”.

2.1 14 + 9 + 4 = _________________

2.2 Halveer 137: _________________

2.3 30 × _________________ = 3000

2.4 (42 ÷ _________________) + 9 = 16

2.5 567 _________________ 23 = 590

2.6 9 × 6 = _________________

2.7 _________________ × 8 = 56

2.8 _________________ - 15 = 285

2.9 80 + 65 + 155 = _________________

2.10 1 003 - 19 = _________________

2.11 72 ÷ 9 = _________________

2.12 (5 × 6) + 13 = _________________

2.13 108 ÷ _________________ = 8

2.14 _________________ ÷ 12 = 6

2.15 Verdubbel 67: _________________

2.16 (5 × _________________) - 9 = 11

2.17 11 × 12 = _________________

2.18 _________________ ÷ 7 = 12

2.19 Rond af tot die naaste 100: 3 550 _________________

2.20 Rond af tot die naaste 1 000: 7 299_________________

Kleur in:

My vorige hoofrekenpunt was: BETER SWAKKER DIESELFDE

3. In hierdie aktiwiteit is dit ook nodig dat jy weer na die waarde en plekwaarde van elke syfer sal kyk. Werk saam met ’n maat en kyk of jul die volgende vrae kan antwoord:

3.1 Watter getal is 1 meer as 9 999?_________________________________

3.2 Watter getal is 10 meer as 9 990?________________________________

3.3 Watter getal is 100 meer as 9 900?_______________________________

3.4 Watter getal is 1 000 meer as 9 000?______________________________

3.5 Die getal 10 000 is 10 meer as __________________________________

4 Kom ons kyk of julle reg was!

TIENDUISENDE

ONTHOU JY NOG?

10 ene = 10 × 1 = 10

10 tiene = 10 × 10 = 100

10 honderde = 10 × 100 = 1 000

4. Kan jy nou die volgende voltooi?

10 duisende = 10 × ......................... = .........................

In die notasiekolom lyk dit so:

× 10 × 10 × 10 × 10
Tienduisende Duisende Honderde Tiene Ene
TD D H T E
10 000 1 000 100 10 1
10 × 10 × 10 × 10 10 × 10 × 10 10 × 10 10 × 1 1 × 1
÷ 10 10 ÷ 10 ÷ 10

explain how nature and nurture affect the development and later the productivity of an individual.
Amesalu Reply
nature is an hereditary factor while nurture is an environmental factor which constitute an individual personality. so if an individual's parent has a deviant behavior and was also brought up in an deviant environment, observation of the behavior and the inborn trait we make the individual deviant.

I am taking this course because I am hoping that I could somehow learn more about my chosen field of interest and due to the fact that being a PsyD really ignites my passion as an individual the more I hope to learn about developing and literally explore the complexity of my critical thinking skills
